Herb Mumford got a new car during the spring of 2005. He wanted to check how many miles per gallon (MPG) his new car would average so he did the following.
- Drove his car until the gas tank got near empty.
- Reset the trip odometer to zero.
- Filled the gas tank to full.
- Drove the car
- Filled the tank again with
13.3gallons of gas.
Now Herb did the following arithmetic to calculate his car's MPG.miles driven: 356.2 gallons of gas used: 13.3 356.2 miles miles per gallon = ------------- = 26.78195488 13.3 gallons rounded down to the nearest tenth of a mile: 26.7 mpg
Herb checked his calcuation using FuelEconomy.gov, which stated his car had the following MPG ratings.MPG (city) 21 MPG (highway) 29 MPG (combined) 24
FuelEconomy.gov:: Find the Estimated MPG for a Car
Herb wanted to know how many miles he could drive on a full tank of gas. He learned that the gas tank of his car has a capacity of
16 gallonsallowing him to do the following computation.capacity: 16 gallons mpg: 26.7 26.7 miles ---------- * 16 gallons = 427.2 miles 1 gallon
Herb's new car can go approximately
427 mileson a full tank of gas.
