Is the average velocity of an object going down an inclined ramp equal to the instantaneous velocity of the object at the midpoint of the ramp? So, I need to verify whether or not the average velocity of an object going down an inclined ramp is equal the instantaneous speed of the object in the midpoint, and I need to figure out a simple way to explain it as well. 

Velocity increases linearly with time. This means that average velocity occurs at the midpoint in time, which is definitely not the same as the midpoint in space.
