A 29 m long train passes a platform which is 100 m long.Find the distance covered by the train in passing the platform.

Answer

To find the distance covered by the train in passing the platform, we need to consider both the length of the train and the length of the platform.

### Step-by-Step Solution:

1. **Identify the lengths involved**:
- Length of the train = 29 meters
- Length of the platform = 100 meters

2. **Understand the total distance to be covered**:
- When the train passes the platform, it must travel the entire length of the platform plus its own length. This is because the front of the train must reach the end of the platform, and then the entire train must clear the platform.

3. **Calculate the total distance**:
- Total distance = Length of the platform + Length of the train
- Total distance = 100 meters + 29 meters

4. **Perform the addition**:
- Total distance = 129 meters

5. **Conclusion**:
- The distance covered by the train in passing the platform is 129 meters.

### Final Answer:
The distance covered by the train in passing the platform is **129 meters**.
