Gavin drove 85 miles on 10 gallons of gas. how many miles can gavin drive on 25 gallons of gas?

212.5 miles on 25 gallons.

Step-by-step explanation:

Set up a proportion

85 miles on 10 gallons

x miles on 25 gallons.

85/10 = x / 25                   Multiply both sides by 25

85*25 / 10 = x                   Simplify the left

2125 / 10 = x

x = 212.5 miles in 25 gallons.
