Answer: The blue car gets 26 2/3 mpg
The silver car gets 34 mpg
The silver car can travel farther on one gallon of gas. By about 7 1/3 miles.
Explanation:
Divide miles by amount of gas.
Blue: 35 1/2 ÷ 1 1/2 = mpg
71/2 ÷ 3/2 => 71/2 × 2/3= 71/3
Simplify 26 2/3 mpg
Silver: 27 1/5 ÷ 4/5 =>136/5 × 5/4
136/4 Simplified = 34 mpg
