Question

An inflatable pool has sprung a leak. You place a 12-ounce cup under the leak and find that it fills

up in 50 seconds. How many gallons per hour is the swimming pool losing?

Answer 1

6.75 gallons lost in 1 hour.

Explanation:

1 US gallon = 128 ounces.

12 ounces takes 50 seconds.

x ounces takes 3600 seconds (which is 1 hour) Cross multiply

12 * 3600 = 50 x

43200 = 50 x Divide by 50

43200 / 50 = x

864 oz = x

So in 1 hour 864 ounces were lost.

Now there are 128 ounces in a gallon

1 gallon /128 ounces = x / 864 Cross multiply

864 * 1 / 128 = x

6.75 = x

There are 6.75 gallons in 1 hour
