Question

Jeremy's car went 300 miles (highway) on 10 gallons of gasoline. What was the average number of miles per gallon?

Answer 1

30 miles per gallon

Explanation:

Answer 2

whenever you see the word "per" you can ALWAYS substitue in the word "divide". When you see "miles per gallon", change "per" into "divided by" to get miles divided by gallons. That is how you will solve the problem.

SO.....
300 miles ÷ 10 gallons = 30 miles per gallon
