To determine the time it will take for a 5-man crew to complete a project with a total of 280 standard hours, it is essential to calculate the total man-hours available for the crew and how that relates to the standard hours required for the project.

First, we need to understand how many hours each crew member is expected to work. Assuming a standard workday is 8 hours, a 5-man crew working together can collectively contribute 40 man-hours in one day (5 crew members x 8 hours each).

Next, we calculate how many days it will take the crew to complete the total of 280 standard hours. By dividing the total standard hours by the daily output of the crew:

280 standard hours ÷ 40 man-hours per day = 7 days.

However, this calculation is based on the crew working at 100% efficiency. If the actual efficiency of the crew is less than 100%, the time required to complete the project will increase accordingly.

Assuming their actual efficiency results in a scenario where you would encounter a multiplier in the calculation, it is essential to find the adjusted number of days based on that efficiency.

If, for instance, the crew is only able to work at 80% efficiency
