Question 864358: please help me solve this problem
One pipe can normally fill a pool in 24 hours. There is a small leak in the pool that would drain a full pool in 36 hours. HOw long would it take to fill the pool if the leak is not patched?
Answer by mananth(16946) (Show Source): You can put this solution on YOUR website!
filling the pool or emptying the pool is one job
filling 24 hours so it does 1/24 of the job in 1 hour
emptying = 36 hours
so the leak does 1/36 of the job in 1 hour
effective job done in 1 hour
1/24 - 1/36
LCM
(3-2)/72
1/72 of the job is done in 1 hour
It will take 72 hours to fill the pool
