Question 1179939: Using pipe A, a pool can be filled with water in 4 hours. Pipe B can drain the pool in 8 hours. If both pipes were accidentally open, how long would it take to fill the pool? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website!
A fills 1/4 of pool in 1 hour
B drains 1/8 of pool in 1 hour
1/4 -1/8 = 1/8
Every hour 1/8 of pool is filled
so it takes 8 hours to fill the pool
