Chapter 4, Problem 76(choose chapter or problem)
The graph shows the fuel consumption π of a car (measured in gallons per hour) as a function of the speed π£ of the car. At very low speeds the engine runs inefficiently, so initially π decreases as the speed increases. But at high speeds the fuel consumption increases. You can see that π(π£) is minimized for this car when v βΒ 30 mi/h. However, for fuel efficiency, what must be minimized is not the consumption in gallons per hour but rather the fuel consumption in gallons per mile. Letβs call this consumption πΊ. Using the graph, estimate the speed at which πΊ has its minimum value.
