Operating a Vehicle – Fuel Economy
A major cost of operating
a vehicle is the fuel cost.
Every vehicle is different
when it comes to number
of litres of fuel needed to
travel 100 km. In an
imperial system fuel
economy is expressed as
miles per gallon.

Expressing Fuel Economy
Fuel economy can be expressed in metric or in
imperial.
Metric: It is expressed in the number or litres of
fuel needed to go 100 km.
Ex. 9.5 L/100 km
Imperial: It is expressed as the number of miles
you can travel on 1 gallon of gas.
Ex. 30 miles/gallon or 30 mpg

Calculating Fuel Economy
Step 1 Filling the
vehicle's gas
tank
completely
and writing
down the
vehicle's
odometer
reading .
Example: The
last time the
tank was
filled, the
odometer
reading was
32,645.1 km.

Step 2 When it's time to
refuel, filling the
tank completely and
writing down the
number of litres it
took to fill the tank
and the vehicle's
new odometer
reading. Once two
odometer readings
are taken, fuel
economy can be
calculated.
Example: The next
time the tank was
filled, the odometer
reading was
33,001.3. It took 55
litres to fill the tank.

Step 3 Calculating
the distance
driven by
subtracting
the new
odometer
reading from
the previous
one.
Example: The
distance
driven would
be 33,001.3
minus
32,645.1, or
356.2
kilometers.

Vehicle
Step 4 Multiply the
number of litres
used by 100 and
divide by the
number of
kilometers
driven. The
result is the
vehicle's fuel
economy for that
driving period.
Example:
(55 L X 100)/
356.2 km.
The fuel
economy for that
driving period
would be
15.4 L/100 km.

Example Problem #5
Gina traveled a total of 350 km in the city; and 200 km on
the highway during one week of driving. Her car has a
fuel economy of 105 L/100 km in the city, and 7.4 L/100
km on the highway. Gasoline costs 62.5 cents per litre.
Calculate the number of litres she used and the cost.

Fuel Economy – Research Activity
Using the internet, research
5 different vehicles,
recording their fuel
economy in litres per 100
km. Calculate the # of litres
required to travel 24 000 km
in one year. Calculate the
cost of fuel, using today's
price of 99.9 cents per litre.
