Gas mileage is the distance you can travel in
your vehicle on one unit volume of gas. In general, it is usually
expressed as miles per gallon (mpg) or kilometers per liter (kpl).
To find the gas mileage, you take the distance you have
traveled-say from Boston to New York-and divide it by the number of
gallons or liters of gasoline that you used.
The equation for finding gas mileage
is:
GM = D/G
where
GM = Gas Mileage
D = Distance Traveled
G = Amount of Gasoline
Rick and his family drove from Los Angeles to San Diego for the
SuperBowl game. The odometer read 22,320 miles at the beginning of
the trip, and 22,560 miles at the end. They used 14 gallons of gas
to travel that distance. On the window sticker of their new car,
the EPA* estimated of 14 mpg in the city and 19 mpg on the highway.
What is the estimated mpg of their car for this trip?
* Environmental Protection Agency
GM = D/G
GM = D/G
GM = (22,560 - 22,320)/14
GM = 240/14
GM = 17 mpg
This mileage is within the EPA estimation.
Chris and his family went to San Francisco for a trip. They came
from San Diego. When the gas tank was filled, the odometer reading
was 10,231.4. When they got to the next gas station, the odometer
read 10,432.6 miles. The average gas mileage of the their car
is 26 mpg and the gas tank has a capacity of 15 gallons. To arrive
at first gas station, he had to fill up his tank. How much gasoline
did they use in the first part of their trip?
Estimate the answer:
 5 gallons of gas
 8
gallons of gas
 15
gallons of gas
 20
