A body covers half of its distance with speed u and the other half with a speed v , the average speed of the body is

Options

  1. A2 u v u+v
  2. Bu-v 2
  3. Cu+v 2 u v
  4. Du+v 2

Correct answer

A. 2 u v u+v

Step-by-step solution

Average speed = Total Distance Time = d ( d / 2 u )+ ( d / 2 v ) = 2 u v u+v
