An athlete complete one round of a circular track of diameter 200m in 40s. What will be the distance covered and the displacement at the end of 2 minutes ?

Explanation

To solve the problem, we need to find the distance covered and the displacement of an athlete who completes one round of a circular track with a diameter of 200 meters in 40 seconds, after 2 minutes.

### Step-by-Step Solution:

**Step 1: Calculate the radius of the circular track.**
- The diameter of the track is given as 200 meters.
- The radius \( r \) is half of the diameter:
