Time taken by a train x metres long to cross a pole = Time taken by the train to cover _______ meters.

Answer

To solve the problem, we need to understand the relationship between the length of the train and the distance it needs to cover to completely cross a pole.

### Step-by-Step Solution:

1. **Identify the Length of the Train**:
The length of the train is given as \( x \) meters.

2. **Understanding the Crossing of the Pole**:
When a train crosses a pole, it needs to cover a distance equal to its own length to completely pass the pole. This is because the front of the train must reach the pole and then the entire length of the train must clear the pole.

3. **Distance Covered to Cross the Pole**:
Therefore, the distance that the train needs to cover to completely cross the pole is also \( x \) meters.

4. **Time Taken to Cross the Pole**:
The time taken by the train to cross the pole is equal to the time taken by the train to cover this distance of \( x \) meters.

5. **Final Conclusion**:
Thus, the time taken by a train \( x \) meters long to cross a pole is equal to the time taken by the train to cover \( x \) meters.

### Final Answer:
The time taken by the train to cover \( x \) meters.
