Question

Samantha's car used 3 gallons to travel 51 miles. At what rate does the car use gas, in miles per gallon?

Answer 1

17 miles per gallon

Explanation:

Divide 51 by 3. Here's a better way to understand it:

Create a ratio to represent miles to gallons: 51-to-3

To find the ratio of miles per gallon, it's implying x miles for 1 gallon. To get this x value, you divide both sides by 3.

51/3 = 17miles/gallon
