In order to find the unit rate for each we neeed to divide the distance eah car traveled by the amount given
for the blue car
[tex]\frac{35\frac{1}{2}mi}{1\frac{1}{4}\text{gal}}=\frac{142}{5}=\frac{28.4mi}{gal}[/tex]for the red car
[tex]\frac{20\frac{4}{5}mi}{\frac{4}{5}\text{gal}}=\frac{26mi}{gal}[/tex]The blue car can travel a longer distance on 1 gallon of gasoline
