Final answer:
It will take 50 minutes for Pools A and B to have the same amount of water, after setting up the equation (900 - 5m = 750 - 2m) and solving for m.
Step-by-step explanation:
To find after how many minutes, m, pools A and B will have the same amount of water, we can set up an equation where the amount of water leaking from Pool A equals the amount of water leaking from Pool B. Initially, Pool A has 900 gallons and Pool B has 750 gallons. Pool A leaks at a rate of 5 gallons per minute and Pool B leaks at 2 gallons per minute.
Let's set up our equations:
- Water remaining in Pool A after m minutes: 900 - 5m
- Water remaining in Pool B after m minutes: 750 - 2m
Setting the two expressions equal to each other because we want the volumes to be equal gives us:
900 - 5m = 750 - 2m
Now we'll solve for m:
900 - 5m = 750 - 2m
5m - 2m = 900 - 750
3m = 150
m = 150 / 3
m = 50
So, it will take 50 minutes for the two pools to have the same amount of water.
