You can put this solution on YOUR website! 10 men complete a job in 14 days
--------------------------------
1 man will take 10 times as long to do the job, so
-------------------------------------------
1 man completes a job in 140 days
----------------------------------------
4 men can complete the job in 1/4 of that time, so
---------------------------------------------
4 men can complete a job in 35 days
Try it this way.
Let r = the rate for ONE man, assuming each man works at this rate.
, doing the one job and using the uniform rate idea, RT=J for rate time job. The factor used with the number r is for how many men are doing work, since the rate of any group is the sum of the individual rates, and all of them being r. is the time, unknown, in days for the group of four men.
