A train 250 m long is running at a uniform speed of 25 m/s, then the time taken by it to cross an electric pole is _______.

Answer

To find the time taken by a train to cross an electric pole, we can use the formula for time, which is derived from the relationship between speed, distance, and time.

### Step-by-Step Solution:

1. **Identify the Length of the Train**:
The length of the train is given as 250 meters.

2. **Identify the Speed of the Train**:
The speed of the train is given as 25 meters per second.

3. **Understand the Concept**:
When the train crosses an electric pole, it needs to cover a distance equal to its own length. Therefore, the distance to be covered is 250 meters.

4. **Use the Formula for Time**:
The formula to calculate time is:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

5. **Substitute the Values**:
Substitute the known values into the formula:
\[ \text{Time} = \frac{250 \text{ meters}}{25 \text{ meters/second}} \]

6. **Calculate the Time**:
Perform the division:
\[ \text{Time} = \frac{250}{25} = 10 \text{ seconds} \]

7. **Conclusion**:
Therefore, the time taken by the train to cross the electric pole is **10 seconds**.
