Question

miles onYou are running a fuel economy study. One of the cars you find is blue. It can travel 352144miles on1ā gallons of gasoline. Another car is red. It can travel 20gallon of gasoline. What is55the unit rate for miles per gallon for each car? Which car could travel the greater distance on 1 gallonof gasoline?

Answer 1

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

`\frac{35(1)/(2)mi}{1(1)/(4)\text{gal}}=(142)/(5)=(28.4mi)/(gal)`

for the red car

`\frac{20(4)/(5)mi}{(4)/(5)\text{gal}}=(26mi)/(gal)`

The blue car can travel a longer distance on 1 gallon of gasoline
