Motorcycle Fuel Efficiency

Jason’s brother has a motorcycle.

The motorcycle can travel 210 miles using 3.5 gallons of gas.

  • Do you think its fuel efficiency will be more or less than that of Jason’s dad’s car? Explain your thinking.
  • Express the fuel efficiency rate in miles per gallon.
  • Express the fuel efficiency rate in gallons per mile.

Hint:

  • What are the two quantities in the problem?
  • If you want to find the rate miles per gallon (mpg), or miles divided by gallons, what quantity must be in the numerator?
  • If you want to find the rate gallons per mile (gpm), or gallons divided by miles, what quantity must be in the numerator?
