You are running a fuel economy study. One of the cars you find is blue. It can travel 45 1/2 miles on 1 1/4 of gasoline. Another car is red. It can travel 23 3/5 miles on 4/5 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

9514 1404 393

Answer:

• blue: 36.4 mpg
• red: 29.5 mpg
• blue goes farther on 1 gallon

Explanation:

You find miles per gallon by dividing miles by gallons. ("Per" essentially means "divided by.")

blue

(45.5 mi)/(1.25 gal) = 36.4 mpg

red

(23.6 mi)/(0.8 gal) = 29.5 mpg

__

"Miles per gallon" is the number of miles traveled on one gallon. The blue car can travel a greater distance on 1 gallon of gasoline.
