If a car uses 4 gallons for 120 miles, what is the miles per gallon?

• A. 25
• B. 30
• C. 40
• D. 50

Answer: (B)

Miles per gallon is a rate that shows how far you can travel on one gallon of fuel. To find it, divide the distance by the gallons used. For 120 miles on 4 gallons, 120 ÷ 4 = 30. So the car gets 30 miles per gallon. The other values would require using more or less fuel for the same distance, which isn’t the case here.
