Since the acceleration is constant, the average velocity is simply the average of the initial and final velocities of the body:

We can proof that the distance covered by the body moving at constant average velocity
is equal to the distance covered by the body moving at constant acceleration a:
- body moving at constant velocity
: distance is given by

- body moving at constant acceleration
: distance is given by

I'm not quite sure what happens to Fay so I didn't finish but hope it helps
Answer:
