Question

One large pipe with cold water and one small pipe with hot water are used to fill a pool. When both pipes are used, the pool can be filled in 2 hours. If only the cold water pipe (large one) is used to fill the pool it can be done in 3 hours. How long would it take to fill the pool with just the hot water pipe?

Answer 1

Answer 2

that is all i got in the problem

Answer 3

1/3 + 1/x = 1/2

Answer 4

It takes the cold water pipe 3 hours to fill the pool. So it does 1/3 of the job per hour
It takes the hot water pipe x hours to fill the pool. So it does 1/x of the job per hour.
It takes both pipes 2 hours to fill the pipe so together they do 1/2 of the job per hour.
1/3+1/x=1/2 just like dockworker said.
