Question

you are running a fuel economy study. One of the cars you find is blue. It can travel 31 1/2 miles on 1 1/4 gallons of gasoline. Another car is red. It can travel 27 1/5 on 4/5 gallon of gasoline. What is the unit rate for miles per gallon for each car? Which car could travel the greater distance on 1 gallon of gasoline?

Answer 1

Explanation:

Blue Car: (31 1/2 miles)/(1 1/4 gallons)

(63/2) miles / (5/4) gallons

(63/2)*(4/5) = 25.2 miles/gallon.

Red Car: (27 1/5 miles)/(4/5 gallon)

= 34 miles/gallon.

The Red Car will travel the furthest.
