Question 775464: Candy and Tim share a paper route. It takes Candy 70 minutes to deliver all the papers, and it takes Tim 80 minutes. How long does it take the two when they work together? Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Candy takes 70 minutes to deliver all the papers.
Tim takes 80 minutes to deliver all the papers
Candy's rate 1/70
Tim's rate 1/80
Combined rate = 1/x
1/70 + 1/80 = 1/x
Common denominator = 5600x
80x + 70x = 5600
150x = 5600
x = 37.3 minutes
x = 37 minutes 20 seconds.
Hope this helps.
