Tanu and Vishu start walking together on a circular path in opposite directions. If they meet after sometime at a particular point, then what is the sum of distances covered by them, given that r is the radius of path?

Options

A. 2 `pi` r
B. `pil`
C. `4 pi r`
D. None of these

Answer

To solve the problem, we need to determine the sum of the distances covered by Tanu and Vishu when they meet while walking in opposite directions on a circular path.

### Step-by-Step Solution:

1. **Understand the Circular Path**:
- The circular path has a radius \( r \).
- The circumference \( C \) of the circular path can be calculated using the formula:
\[ C = 2\pi r \]

2. **Walking in Opposite Directions**:
- Tanu and Vishu start walking in opposite directions. This means that the distance they cover will add up as they walk towards each other.

3. **Meeting Point**:
- When they meet, they will have covered a total distance equal to the circumference of the circular path. This is because they are walking towards each other and will meet at some point along the path.

4. **Sum of Distances**:
- Since they meet after covering the entire circumference, the total distance covered by both Tanu and Vishu together is:
\[ \text{Total Distance} = C = 2\pi r \]

### Final Answer:
The sum of the distances covered by Tanu and Vishu when they meet is \( 2\pi r \).
