Question

Two pools are leaking, after 15 minutes pool A has leaked 2/3 gallon, after 20 minutes pool B has leaked 2/3 gallon. Which pool is leaking water the fastest and by how much?

*20 points* please answee quick!

Answer 1

Pool A.

Explanation:

This can be solved through ratios. You would write it as
`(gallons)/(minutes)` So,
`(2/3)/(15)` for the first one, and
`(2/3)/(20)` for the second. You might want to use a calculator for that part, but you could also change the gallons to cups, which gives you a much better number of 10.515. So,
`(10.515)/(15) = 0.701`, and
`(10.515)/(20) = 0.52575` So, pool A is at a faster rate. If you want it in gallons per minute, it's by 0.01 (with the 1 repeating) gallons per minute. By cups, it's 0.17525 cups per minute.

(The reason I did not do this by cross multiplying and dividing ratios is because it gives you the exact same answer if you are finding it per one, as I am here with per one minute. You can do it this way, it just wastes a bit of time.)
