Part (A)
The blue car travel 38.5 miles on 1.25 gallons of gasoline
∴ The unit rate of the blue car = 38.5 ÷ 1.25 = 30.8 miles per gallon
==========================================
Part (B):
The red car travel [tex]23 \frac{1}{5}[/tex] miles on [tex]\frac{4}{5}[/tex] gallons of gasoline.
[tex]23 \frac{1}{5}[/tex] = 23.2 and [tex]\frac{4}{5}[/tex] = 0.8
∴ The unit rate of the red car = 23.2 ÷ 0.8 = 29 miles per gallon
==========================================
Part (C):
Which car could travel the greater distance on 1 gallon of gasoline?
The answer: by reviewing part (A) and part (B)
So, the blue car can travel the greater distance on 1 gallon of gasoline.
