You are running a fuel economy study. One of the cars you find is blue. It can travel on of gasoline. Another car is red. It can travel on of gasoline. What is the unit rate for miles per gallon for each car?

Blue car = 28.4 miles per gallon

Red car = 34 miles per gallon

Step-by-step explanation:

You are running a fuel economy study. One of the cars you find is blue. can travel 35 1/2 miles on 1 1/4 gallons of gasoline. Another car is red. It can travel 27 1/5 miles on 4/5 gallons of gasoline.

What is the unit rate for miles per gallon for each car?

Blue car:

Travels 35 1/2 miles on 1 1/4 gallons of gasoline

Miles per gallon of the blue car = Total miles / total gallons

= 35 1/2 miles ÷ 1 1/4 gallons

= 71 / 2 miles ÷ 5/4 gallons

= 71/2 × 4/5

= 284 / 10

= 28.4 miles per gallon

Red car:

Travels 27 1/5 miles on 4/5 gallons of gasoline

Miles per gallon of the red car = Total miles / total gallons

= 27 1/5 miles ÷ 4/5 gallons

= 136 / 5 ÷ 4/5

= 136/5 × 5/4

= 136 / 4

= 34 miles per gallon
