The model S (d)= 30df represents the speed S (in miles per hour) of a van before it skids to a stop, where f is the drag factor of the
road surface and d is the length (in feet) of the skid marks. The drag factor of Road Surface A is 0.75. The graph shows the speed of the
van on Road Surface B. Compare the speeds by finding and interpreting their average rates of change over the interval d=0 to d=15.
