Question 1006885: 3 men can cut 15 trees in 2 hours. if two men leave the job,how many trees will be cut in 3 hours
Answer by rothauserc(4718)   (Show Source):
You can put this solution on YOUR website! It takes 3 men working 2 hours to cut 15 trees, therefore
It takes (3 * 2) man hours to cut 15 trees,
It takes 6 / 15 or 2/5 man hour to cut one tree
***********************************************************
now 1 man working 3 hours is 3 man hours, therefore
3 / 2/5 = (3 * 5) / 2 = 7.5 trees
7.5 trees are cut by 1 man working 3 hours
