Question

Swimming pool A contains 30 gallons of water and is filling at a rate of 3 gallons per minute.

Swimming pool B contains 18 gallons of water and is filling at a rate of 5 gallones per minute.
Enter the number of minutes it will take for both swimming pools to contain the same amount of water

Answer 1

6 Mins

Explanation:

I like to solve these questions with a equation.

I form the equations with Orginal Amount + FlowingRateX.

Since we have 2, and we want them to be the same they will be equal to eachother.

30+3x=18+5x

12=2x

x=6
