A car travels 84 mi on 3 gal of gas
how would I do this?
find the unit rate.
What do you need to do?
84 / 3 = _____ miles per gallon
To find the average miles per gallon (MPG) that the car travels, divide the total distance traveled by the total amount of gas consumed. In this case, the car traveled 84 miles on 3 gallons of gas.
To calculate the MPG, divide 84 miles by 3 gallons:
MPG = 84 miles / 3 gallons
