2 Fuel Consumption as a Rate (1/5) End of Slide Amount of Fuel in Litres [Number of Kilometres ÷ 100] Fuel Consumption = Fuel Consumption = Litres / 100 km. (This is a Rate) Example: Mary drove 900 km from Sydney to Brisbane and used 72 litres of petrol. What was her fuel consumption? Fuel Consumption = 72 Litres [900 km ÷ 100] = 8 L/100 km Question 3
