PLEASE HELP!! BRAINLIEST 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. Round your answers to the nearest hundredth.
