Reuben drove 240 miles using 9 gallons of gas. At this rate, how many gallons of gas would he need to drive 216 miles

Question

How many gallons

Answer 1

Great question!

 

First find the rate: 240 miles/9 gallons = 26.7 miles/gallon. So this means Reuben can drive 26.7 miles per 1 gallon.

There are 216 miles that he needs to drive. So, 216/26.7= 8.1 gallons needed (answer is rounded)
