Relative Speed, Clocks and Circular Motion

The concept of relative speed is not a new or extra concept that CAT 2007 or 2008 aspirants need to learn. It is still the basic time, speed and distance formula applied to distance between two moving bodies. In a simple case of the distance formula, a body traveling with a speed of 50 km/h is reducing the gap between its starting point and the finish point by 50 km every hour. In the relative speed case of the distance formula two moving bodies, traveling at a relative speed of 50 km/h towards/away from each other, are reducing/increasing the gap between them by 50 km every hour.

Let me explain this through an example:
