<PRE><B>Question 939769</B>
A faucet filled a 315 gallon tank in 9 hours. Later, the tank suffered a crack at the bottom and started leaking at the rate of 6 gallons per hour. How long will it take the faucet to refill the emptied tank? 
----
Original condition rate:: (1/9)315 = 35 gallons/hr
------
Leaking at 6 gallons/hr
------
Effective rate using faucet at time of leak:: 35-6 = 29 gallons/hr
----
Ans: # of hours to fill 315 tank:: 315/29 = 10.86 hrs = 10hrs 51min 36sec
