Question

How to find average speed?

Answer 1

If initial speed (u) and final speed (v) are given of any moving object or body with respect to total time (t) of the duration of body (total time of body during the motion), then the sum of initial and  final speed with respect to total time taken by body is the average speed of the moving body (object/particle).

Formulating the given statement,
(u+v)/t
