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

Answer:

25 seconds

Step-by-step explanation:

You have a rate of:

$\dfrac{1}{5}gal/s$

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:

$5gal\times\dfrac{1sec}{\frac{1}{5}gal}=\dfrac{5sec}{\frac{1}{5}}=25sec$
