On this appeal, we are limited to determining whether the Industrial Commission’s findings of fact are supported by competent evidence and whether the conclusions of law based on the facts found are correct. Inscoe v. Industries, Inc., 292 N.C. 210, 232 S.E. 2d 449 (1977). We hold that the findings of fact are supported by competent evidence and the conclusions of law are correct.
The defendants have excepted to the following facts found by the Hearing Commissioner: (1) “Decedent was permitted by the written regulations of the defendant employer to use the swimming facilities at the lake when off-duty.” (2) “There is no evidence that plaintiff was ever instructed that the lake was closed during lunch period or what constituted the ‘chained area’ of the lake.” (3) There is no evidence “. . . that [decedent] was familiar with the way the lake was arranged for swimming,” and (4) “There is no evidence of record that there were any signs posted to indicate . . . that the lake was closed at the time the decedent entered it.”
As to finding number (1) above, the defendants contend there is nothing in the record to support a finding that the decedent was permitted by written regulations to use the swimming facilities. Conceding without deciding the point that he was not permitted by written regulations to do so, there is substantial evidence that he had permission to use the swimming facilities *492and if the words “by written regulations” are struck from this finding of fact, it does not affect the outcome of this case.
As to finding of fact number (2) above, Guy Hill Jones, decedent’s superior testified: “I never gave them any instructions either way on swimming.” Mr. Mace’s testimony was that the resident staff received instructions. The decedent was not a member of the resident staff. The defendants argue that the posted sign and the lay out of the lake itself, including the chained area, is enough to invalidate this finding. We believe the Hearing Commissioner was reasonable in his conclusion that there had to be an actual imparting of information from one person to another in order to find there had been an instruction.
As to finding number (3), the defendants argue that the fact the decedent had worked around the lake and had talked to the lifeguard while the lifeguard was on-duty invalidates this finding. We cannot hold the Hearing Commissioner erred in making such a finding on this evidence.
As to finding number (4) above, the evidence was that the lifeguard had taken the buoys out of the water. There is no evidence that he or anyone else had posted a sign that the lake was closed.
The defendants have also taken exception to a finding denominated by the Hearing Commissioner as a conclusion of law as follows: “The circumstances of the drowning are that the decedent was using facilities authorized by the employer for his use. Although there was a regulation that the lake was closed during the lifeguard’s lunch hour, that regulation was never communicated to the decedent.” We believe this conclusion is amply supported by competent evidence.
 The defendants contend that the accident which caused the death of Vincent Keith Martin was not one “arising out of or in the course of” his employment. These words, which are found in G.S. 97-2(6) have been interpreted many times. See all the cases cited in this opinion and also Harless v. Flynn, 1 N.C. App. 448, 162 S.E. 2d 47 (1968). The phrases “arising out of” and “in the course of” are not synonymous and both must be fulfilled in order for the plaintiffs to recover.
An accident arises out of employment when it is the result of a risk or hazard incident to the employment and is not from a *493hazard common to the public. There is no evidence in this case that the public was invited to swim in the lake. Accidents while swimming were a hazard for employees of the Assembly and not to the public at large. The accident arose out of the decedent’s employment.
In this jurisdiction, three conditions must be fulfilled in order for an accident to be in the course of employment. These three conditions are of time, place, and circumstance. “Time” includes the time during a working day including the lunch hour. “Place” includes the premises of the employer. Clearly both these conditions are fulfilled in this case.
In respect to “circumstances,” compensable accidents are those sustained while the employee is doing what a man so employed may reasonably do within a time which he is employed, and at a place where he may reasonably be during that time to do that thing. In view of the finding that decedent was authorized by the Assembly to swim in the lake during his lunch hour and that the regulation prohibiting swimming when the lifeguard was not on-duty had not been communicated to him, we hold the condition of “circumstance” is fulfilled.
The defendants cite several cases which they contend should govern and preclude recovery by the plaintiffs. Among these cases are Robbins v. Nicholson, 281 N.C. 234, 188 S.E. 2d 350 (1972); Horn v. Sandhills Furniture Co., 245 N.C. 173, 95 S.E. 2d 521 (1956); Moore v. Stone Company, 242 N.C. 647, 89 S.E. 2d 253 (1955); Matthews v. Carolina Standard Corporation, 232 N.C. 229, 60 S.E. 2d 93 (1950); Morrow v. State Highway and Public Works Commission, 214 N.C. 835, 199 S.E. 265 (1938); Teague v. Atlantic Co., 213 N.C. 546, 196 S.E. 875 (1938). We believe that all these cases are distinguishable. Each of them had some factor not present in this case which precluded coverage for the plaintiff. In Robbins it was held not to be a risk of employment to be killed by a jealous husband of a co-worker. In Horn, an employee crossing a public street to eat lunch was struck by an automobile. This was held a risk to which the public at large was subject and not limited to employees of the defendant. In Moore, the plaintiff, while eating lunch, out of curiosity set off 300 dynamite caps. It was held the plaintiff was not authorized to play with dynamite caps while eating lunch. In Matthews, the employee, during his lunch break, tried to jump on a truck that was moving on his *494employer’s premises. It was held this was not a hazard incident to his employment. In Morrow, the deceased jumped into a river to recover a paint brush after being told not to do so by his foreman. In Teague, a death was held not to arise out of employment when the deceased, contrary to the rules of his employer, tried to ride a crate conveyor to the second floor of the building rather than using the stairs.
In the case at bar, ■ the Hearing Commissioner has found, based on competent evidence, and the Industrial Commission has adopted his findings, that Vincent Keith Martin, while employed by Bonclarken Assembly, was drowned while swimming during his lunch hour in a lake on the premises of the Assembly. It was also found, based on competent evidence, that the decedent was authorized by his employer to swim in the lake and although the written regulations prohibited Vincent Keith Martin from swimming while the lifeguard was not on-duty, this part of the regulations was never communicated to deceased. Based on these findings, the plaintiffs are entitled to death benefits.
 The defendants’ last assignment of error relates to the amount of the award. The Hearing Commissioner awarded to the plaintiffs the sum of $60.00 per week for 400 weeks. It is obvious he calculated this sum at the rate of $2.25 per hour for a forty-hour week. The evidence was that decedent, a minor, was earning $2.00 per hour.
The language of G.S. 97-2(5) applicable at the time of this suit stated:
Where a minor employee, under the age of 18 years, sustains a permanent disability or dies, the compensation payable for permanent disability or death shall be calculated, first, upon the average weekly wage paid to adult employees employed by the same employer at the time of the accident in a similar or like class of work which the injured minor employee would probably have been promoted to if not injured, or, second, upon a wage sufficient to yield the maximum weekly compensation benefit.
The evidence was that the decedent’s father, who did the same type of work as the decedent, was making more than $2.00 per hour, but not as much as $2.50 per hour. We hold that this *495evidence supports a finding by the Hearing Commissioner of an award based on $2.25 for a wage for a class of job the decedent “would probably have been promoted to.”
