An empty pool being filled with water at a constant rate takes 5 hours to fill to 3/5 of its capacity. How much more time will it take to finish filling the pool?
Choose the correct choice:
A) 5 hr 30 min
B) 5 hr 20 min
C) 4 hr 48 min
D) 3 hr 20 min
E) 2 hr 40 min
(3/5) of a pool/ 5 hours = 3/25 (the rate)   (3 pools/25 hours) = (2/5* pool)/ x hours   Cross multiply 3x = (2/5) 25   x = 3 1/3   1/3 of an hour = 20 minutes   3 hr 20 min
