Question

You find out your sprinkler is leaking 8 pints of water every 2 hours. After 3 hours, how many gallons of water will have leaked from the sprinkler

Answer 1

In 2 hours -- 8 pints of water is lost.

Hence,

In 1 hour --
`(8)/(2)` = 4 pints of water is lost.
[ Dividing by 2 on both sides ]

Thus,

In 3 hours -- 4 * 3 = 12 pints of water is lost.

Answer 2

8/2 = 4 pints per hour

3*4 = 12 pints in 3 hours

there are 8 pints in 1 gallon

12/8 = 1.5 gallons in 3 hours
