Question: how to calculate distance from velocity and acceleration?
Answer: Average Velocity. va = (v1 + v0) / 2 (1) ... 
Final Velocity. v1 = v0 + a t                   (2) ... 
Distance Traveled. s = (v0 + v1) t / 2 (3) ... 
Acceleration. a = (v1 - v0) / t (4) ... 
Example - Accelerating Motorcycle.
