Question

Sandy's car can travel 42 miles on 1 1/6 gallons of gas. At that rate, how many miles per gallon does her car get?

Answer 1

We simply have to divide the total miles that the car can travel by the total amount of gallons of gas.
So,
42 miles/ (11/6 gallons) = 22.91 miles per gallon

Therefore, Sandy's car gets 22.91 miles per gallon of gas
