FUEL ECONOMY

One of the LARGEST costs of owning and operating a vehicle is FUEL.

The # of litres of fuel that a vehicle needs to travel 100 km is called its FUEL ECONOMY.

FUELECONOMY =

litres of fuel used * 100

km driven

Did you also know that F.E. is better on the highway than in the city because there are less stops and turns and you can travel at a higher speed, constantly.

FIRST SOME WARM UP QUESTIONS WITH BASIC EVERY DAY VEHICLE USE...

EX Calculate the total distance travelled based on the following odometer readings:1st: 014569.2 km 2nd: 015498.4 kmFYI: An odometer keeps track of how many km a vehicle has travelled and is located on the dashboard of most vehicles.

EX A car needs 46 L of gas to fill up. If gas costs 79.9 cents per L, what is the cost of filling up?

EX A car travelled 503 km before stopping to fill up. If 31.8 L of gas were pumped into the vehicle, find the fuel economy and the cost to fill up ifgas costs 68.8 cents per L.

EX Sarah travelled a total of 250 km in the city and 150 km on the highway.Her F.E. in the city is 11.7 L / 100 km and 6.4 L / 100 km on the highway.If gas cost her 72.4 cents per L, find the total # of L of fuel she used andthe cost of the fuel.
