The gas tank of your parents car holds 12.9 gallons of gas. Because their car averages 27.8 miles per gallon, how many times will they have to fillup the gas tank to drive to cincinnati and back? From Detroit, Michigan to Cincinnati, Ohio = 264.1 miles.

264.1/27.8 equals the number of gallons used.
divide that by 12.9
