Question 904592: It takes Amy twice as long to deliver papers as it does Nancy. How long would it take each girl to deliver the papers by herself if they can deliver the papers together in 16 minutes? Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! x Nancy's time alone
1/2x + 1/x = 1/16
8 + 16 = x
x = 24min, Nancy's time alone. Amy alone takes 48min
And...
1/48 + 1/24 = 1/48 + 2/48 = 3/48 = 1/16
