Fuel Efficiencies of Two Cars 20- \Car B Car A 10- 80 120 Speed (km/h) 40 4. This graph shows how the fuel consumptions of two vehicles change as their speed increases. a) Describe the trends in each graph. b) When does the fuel efficiency for each vehicle increase or decrease rapidly? When does it increase or decrease at a constant rate? How do you know? c) Which car is more fuel efficient at each speed? i) 55 km/h ii) 110 km/h d) Nara thinks the graph for car B appears to be quadratic. Do you agree or disagree? Justify your answer Fuel consumption (L/100 km)
