<PRE><B>Question 781372</B>
Amanda has a swimming pool that is 20 feet by 20 feet by 8 feet. She is filling the pool using 3 garden hoses with a rate of flow of 1.5 cubic feet per minute. 
A. How long will it take to fill the pool 3/4 of the way?
-----
time = [(3/4)*20*20*8]/(3*1.5) = 533 1/3 minutes
----------------------------- 
B. how long will it take to fill the pool completely if Amanda only uses 2 of the hoses?
time = [20^2*8]/[2*1.5] = 1066 2/3 minutes
---------------------
Cheers,
Stan H.
