Understanding Fuel Efficiency: How 30 MPG and 15 Gallons Equal 450 Miles When calculating how far a car can travel based on fuel efficiency and fuel capacity, understanding the math behind these numbers is key. One essential equation is:
30 miles per gallon (mpg) × 15 gallons of fuel = 450 miles.
This formula reveals how fuel efficiency and tank size work together to determine driving range—information every driver should know to plan journeys, save money, and maximize vehicle performance. ### What Does 30 MPG Mean? Miles per gallon (mpg) measures a vehicle’s fuel efficiency—the distance a car travels per gallon of gasoline consumed. A rating of 30 mpg means your vehicle efficiently covers 30 miles on every gallon of fuel, a standard measure used to compare cars and estimate fuel costs over distance.
