a garden hose can fill a pool in 3 days and a longer one can bill the pool in 2 days. How long will it take to fill the pool if both hoses are used.

In six days, the garden hose can fill 2 pools, and the longer one can fill 3 pools.
So in six days, both can fill five pools, or each pool takes 6/5 day 
day in a half
