Pipe A runs 30 liters of water per minute out of a pool that has a total volume of 3,600 liters. Pipe B empties a third of the pool in 6 hours.
Working together how long will it take both pipes to empty the pool?	Choose the correct choice from the following.
A) 2 hours and 36 minutes  B) 1.5 hours  C) 9 hours and 12 minutes  D) 15 hours  E) 1 hour and 48 minutes.
Pipe A has a rate of 30 liters per minute which equals a rate of 1800 liters per hour.   Pipe B has a rate of 200 liters per hour.   200 + 1800 (A+B) = Together they have a rate of 2000 liters per hour.   3600 (The pool) / 2000 = 9/5 = 108 / 60 = 1 Hour and 48 minutes   Answer -1 hour and 48 minutes.
