Question 9 For a car driven 100 kilometers at a constant speed, the amount of fuel used as a function of the speed is modeled by a differentiable function F. Fuel is measured in liters, and speed is measured in kilometers per hour (km/hr). In this context, which of the following is a correct interpretation of the statement F\" (50) > F/ (80) 7 (,9 Driving at 50 km/hr uses more fuel than driving at 80 km/hr The rate at which 50 liters of fuel is used is greater than the rate at which 80 liters of fuel is used The rate of change of the speed is greater when driving at 50 km/hr than when driving at 80 km/hr, The rate of change of liters of fuel used with respect to the speed is greater when driving at 50 km/hr than when driving at 80 km/hr
