If it takes 2.6 hours to install outlets in each room, how many rooms can be completed in 5 days with men working 8 hours a day?

To determine how many rooms can be completed in 5 days with men working 8 hours a day, we first need to calculate the total number of work hours available in that period.

Since there are 5 days and each workday consists of 8 hours, the total work hours would be:

Total work hours = 5 days × 8 hours/day = 40 hours

Next, since it takes 2.6 hours to install outlets in each room, we can find out how many rooms can be completed in the total work hours available:

Number of rooms = Total work hours / Time per room

Number of rooms = 40 hours / 2.6 hours/room ≈ 15.38

Since only whole rooms can be completed, we round down to the nearest whole number, resulting in a maximum of 15 completed rooms. This calculation clearly shows how the total number of rooms is derived from the available work hours and the time taken for the task per room. Therefore, the answer of 15 rooms is justified based on this accurate computation.
