Question 157307: One pipe can fill a tank in 6 hours, and another pipe can fill the same tank in 8 hours. How long will it take to fill the tank if both pipes are used? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! In words:
(rate for pipe #1) + (rate for pipe #2) = combined rate
or
(1 tank / 6 hours) + (1 tank / 8 hours) = 1 tank / x hours) hrs answer
