4 4+6
---- = ----------
5 AC
4 10
---- = ----------
5 AC
Using cross products
4 * AC = 5*10
4AC = 50
Divide by 4
AC = 50/4
AC =12.5
Since you have the square root of x, you would need to square it to reverse the square root, and just have x. Then, you would have to square the 4 on the otherside, to get x=16
150 minutes. (15,000/2)=7,500 which is 1/2 of the pool. If it fills 50 gallons per minute you’ll want to divide that by 50;(7,500/50) which equals 150
