Vehicle April7

  1. 1. Fuel Economy -What is the most expensive price you have seen for gas this year? What is the cheapest? -What are some of the reasons that fuel prices change over a year? 1
  2. 2. Odometer Readings The odometer conveys how far a car has travelled over its lifespan. ex. 57 000km Example 1: Archie went on a road trip. When he left for the trip the odometer reading on his car was 89 372km. When he stopped to fill his car for gas the odometer reading was 89 722km. How far did Archie travel? 2
  3. 3. Fuel Economy is expressed as the number of litres consumed to travel 100km. -Ex. 14L/100km. This means that a vehicle consumes 14 L of fuel for every 100km travelled. Which car has the best fuel economy: -Car A: 8L/100km -Car B: 6.8L/100km -Car C: 11.5L/100km 3
  4. 4. A car with a full tank of gas travelled 572 km before stopping at a gas station. The car required 41.2L of gas to fill the tank. a) Find the fuel economy of the vehicle. b) Find the cost of fuel for the trip if the cost per litre is 56.3 cents. a) Fuel Economy = litres x100 kilometers driven 4
  5. 5. b) find the cost of fuel for the trip if fuel costs 56.3 cents per litre. *NOTE* - Cost of fuel should be expressed in Dollars ($). Cost = Litres consumed x Price per litre 5
  6. 6. *Note*- a car can have different a different fuel economy at a given time depending on how an individual drives. Archie travelled a total of 350km in the city at 10.5L/100km, and 200km at 7.4L/100km on the highway in one week of driving. Gasoline costs 62.5 cents per litre. a) Calculate the number of litres of fuel used b) Calculate the cost of the fuel. 6
  7. 7. Archie travelled a total of 350km in the city at 10.5L/100km, and 200km at 7.4L/100km on the highway in one week of driving. Gasoline costs 62.5 cents per litre. a) Calculate the number of litres of fuel used Litres needed for city = 10.5L x 350km = 36.75L 100km Litres needed for the highway = 7.4L x 200km = 14.8L 100km Total Litres needed = 36.75 + 14.8 = 51.55L 7
  8. 8. Archie travelled a total of 350km in the city at 10.5L/100km, and 200km at 7.4L/100km on the highway in one week of driving. Gasoline costs 62.5 cents per litre. b) Calculate the cost of the fuel. Total cost = litres used x cost of gas/litre 8
