Question 497629: With water from one hose, a swimming pool can be filled in 9 hours. A second, larger hose used alone can fill the pool in 2 hours. How long would it take to fill the pool if both hoses were used simultaneously? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! The rate of filling for the smaller hose is ( 1 pool / 9 hrs)
The rate of filling for the larger hose is ( 1 pool / 2 hrs)
Let = time to fill pool using both hoses
Multiply both sides by hrs
With both hoses, the pool is filled
in 1 hr 38 min 11 sec
