*15 points* for both ramp heights, you calculated the average speed for the car's entire motion (both on
the ramp and the floor), as well as the average speed for two intervals of the same motion
(interval on the ramp and interval on the floor). write a brief paragraph on how these
"intervals" describe the car's motion more accurately than the average speed of the
entire motion. be sure to explain how this accuracy could have been improved by breaking the
car's motion down into even smaller intervals.
