A car travels 300 miles on 15 gallons of gas
that's a rate of
300mi/15gal = 20 mi/gal
To determine the fuel efficiency, or the miles per gallon (MPG), of the car, you simply divide the total distance traveled (300 miles) by the amount of fuel used (15 gallons).
The formula to calculate MPG is:
MPG = Total distance / Amount of fuel used
In this case, the total distance is 300 miles and the amount of fuel used is 15 gallons. Plugging these values into the formula, we get:
MPG = 300 miles / 15 gallons
Simplifying the equation, we have:
MPG = 20 miles per gallon
Therefore, the car has a fuel efficiency of 20 miles per gallon.
