Do the 5 men work 24 hours each day for 5 days?

one man will take five times as many days as five men, so twenty-five 24 hour days

if the one man only works 8 hrs per day, then it takes seventy-five 8 hr days

I don't see what's wrong with your answer


another approach ___ (5 men)(24 hr / day)(5 days) = 600 man-hrs

(600 man-hrs) / (1 man) / (8 hrs / day) = 75 days
