Question

A man moves from A to B in a straight line and then moves from B to C where C is the mid point of the line. If the average velocity of the particle from A to C through B is v. Let the average speed of the particle for this motion is kv. The value of k.

Let AC = x, so AB = 2x. Displacement = x and distance = 2x + x = 3x. v = t x ​ k v = t 3 x ​ so k v = 3 v , giving k = 3. Answer: 3
