Question

a broken pipe was leaking water at the rate of 2gal every 5 minutes. it took 23 min to stop the leak. how many gallons of water were wasted?

Answer 1

Leaking water has the rate of 2 gal per 5 minutes which is the same as :
2 gal ÷ 5 minutes = 0.4 gal/minute
Then we multiply it by the number of minutes which is 23 as follows :
0.4 gal/minute × 23 minutes = 9.2 galons wasted during the 23 minutes
