If a vehicle travels 240 miles by using 8 gallons of gasoline, what is the fuel efficiency in miles per gallon?

To determine the fuel efficiency in miles per gallon (MPG), you divide the total distance traveled by the total gallons of gasoline used. In this case, the vehicle travels 240 miles and uses 8 gallons of gasoline.

The calculation is straightforward:

Fuel Efficiency (MPG) = Distance Traveled (miles) / Gallons Used (gallons)

Substituting the values:

Fuel Efficiency = 240 miles / 8 gallons = 30 MPG

This means the vehicle is able to travel 30 miles for every gallon of gasoline it consumes, which is the correct and appropriate measure of fuel efficiency. Thus, 30 MPG accurately reflects the vehicle's performance in terms of its fuel consumption relative to distance traveled.
