Question 406178: a faucet in a large tank can fill the tank in 12hrs. However there is a hose in the tank which would be able to empty the tank in 18hrs. If someone left both hoses on how long would it take to fill the tank using the faucet
Answer by Alan3354(69443) (Show Source): You can put this solution on YOUR website!
Each hour, the faucet fills 1/12 of the tank, and the hose loses 1/18 of the tank
1/12 - 1/18 = 1/36 net gain per hour.
--> 36 hours
