1285
liters of water and the second pool contains
1600
liters of water. Water is being added to the first pool at a rate of
32.75
liters per minute. Water is being added to the second pool at a rate of
22.25
liters per minute.

1. After how many minutes will the two pools have the same amount of water?

Volume of first pool  -  V1(t) = 1285 + 32.75t
Volume of 2nd pool  -  V2(t) = 1600 + 22.25t

Find t when V1 = V2 

Equating we get  -   1285 + 32.75t = 1600 + 22.25t
Solving for t we get   87.14 minutes

To find the Volume just substitute this value of t in one of the equations
