Question

Tiffany is filling her daughter's pool with water from a hose. She can fill the pool at a rate of LaTeX: \frac{1}{5}1 5gallons/second. a. At this rate, how long will it take her to fill the pool with 5 gallons of water?

Answer 1

25 seconds

Explanation:

You have a rate of:

`(1)/(5)gal/s`

And you want to find how many seconds it would take to fill in 5 gallons of water. Using the rate, we use it as a conversion factor from rate to seconds:

`5gal*(1sec)/((1)/(5)gal)=(5sec)/((1)/(5))=25sec`
