If a cost estimate assumes that 240 hours will be expended on a given activity, and the projected crew size expected to perform that activity is 5 personnel working and 8-hour workday, what is the calculated duration for the activity?
Correct Answer: B
To calculate the duration: Total hours required: 240 hours. Daily work hours per crew: 5 workers × 8 hours/day = 40 hours/day. Duration = Total hours ÷ Daily work hours = 240 ÷ 40 = 6 days. This calculation aligns with standard resource planning principles.
