Hi, the average speed should always be V/2. Let's suppose we take N speed samples. The space traveled in N T seconds time will be Sum[V_i T] = T Sum[V_i] for i going from 1 to N. So the average speed will be Sum[V_i T] Sum[V_i] V_max ---------------- = ----------------- = (in the limit N->\infinity) ------------ N T N 2 Bye.
