New York State Master Electrician Practice Exam

If it takes an electrician 2.6 hours to install outlets in each room and he works 8 hours a day for 5 days, how many rooms can he complete?

1. 10 rooms

2. 12 rooms

3. 15 rooms

4. 18 rooms

The correct answer is: 15 rooms

To determine how many rooms the electrician can complete, first calculate the total number of hours he works over the 5 days. If he works 8 hours a day for 5 days, that results in: 8 hours/day * 5 days = 40 hours. Next, since it takes 2.6 hours to install the outlets in each room, we can find out how many rooms he can complete in those 40 hours by dividing the total hours worked by the time it takes per room: 40 hours ÷ 2.6 hours/room = approximately 15.38 rooms. Since the electrician cannot complete a fraction of a room, we round down to the nearest whole number, which is 15 rooms. Therefore, the correct answer is based on how many complete installations he can achieve within the working hours provided. This context shows that 15 is the maximum number of complete installations possible within the given work schedule.
