Question 645364: umhh another problem sir, hehe I gone crazy just to solve this problem but still I can't solve it. Can you help me?? The problem goes like this: "One pipe can fill a pool 1.25 times faster than a second pipe. When both pipes are opened, they fill the pool in five hours. How long would it take to fill the pool if only the slower piped is used?" Thank you so much!!! :D
You can put this solution on YOUR website! One pipe can fill a pool 1.25 times faster than a second pipe. When both pipes are opened, they fill the pool in five hours. How long would it take to fill the pool if only the slower piped is used?
.
Let s = time (hours) it takes for slower pipe to fill alone
then
1.25s = time (hours) for faster pipe alone
.
5(1/s + 1/(1.25s)) = 1
multiply both sides by 1.25s to get:
5(1.25 + 1) = 1.25s
5(2.25) = 1.25s
11.25 = 1.25s
11.25/1.25 = s
9 hours = s
