# How long will you chase?

A boy runs on a circular path of radius $$R=28\text{ meters}$$ with constant speed $$u=4 \text{ m/s}$$.

Another boy starts from the center of the circle to catch the first boy. The second boy always moves towards the first one. and maintains a speed of $$v = 4\text{ m/s}$$. How long will the chase last in seconds?

Details and Assumptions:

1) Ignore air friction.

2) Take $$\pi = \dfrac{22}7$$.
