Answer 1

9514 1404 393

Answer:

• blue: 33.2 mpg
• red: 31.0 mpg
• blue travels farther

Step-by-step explanation:

The "unit rate" of interest is "miles per gallon." It is found by dividing miles by gallons.

  blue car: (41.5 mi)/(1.25 gal) = 33.2 mi/gal

  red car: (24.8 mi)/(0.8 gal) = 31.0 mi/gal

  blue car can travel farther on 1 gallon of gas
