 Question 248635: A 3-men crew can do a certain job in 3 weeks and 2 days, if we are to hire 4 men crew instead, with the same rate as the first crew, how long would it take the 4-men crew to do the same job? Note: a week contains 6 working days and a work day is 8 hours.Answer by josmiceli(9819)   (Show Source): You can put this solution on YOUR website!A good question to ask is: If 3 men can do a job in a certain time, how long will it take 1 man to do the job working alone? given: A 3-men crew can do a certain job in 3 weeks and 2 days Using logic, it will take 1 man 3 times as long to do the same job So, 1 man will take 9 weeks and 6 days to do the job (9 weeks) x (6 working days/week) = 54 working days 54 days + 6 days = 60 days (60 days) x (8 hours/day) = 480 hours ----------------------------- Using logic again, It will take 4 men 1/4 of the time that it takes 1 man to do the job hrs (120 hrs) x (1 day/8 hrs) = 15 days (15 days) x (1 week/6 days) = 2.5 weeks (.5 weeks) x (6 days/week) = 3 days It will take the 4 men 2 weeks and 3 days to do the job
