Answer

To determine the unit in which the distance between Delhi and Mumbai is usually expressed, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Distance**: The distance between Delhi and Mumbai is quite large, approximately 1,400 kilometers.

2. **Evaluate the Options**: We have four options to consider for the unit of distance:
- Option 1: Decameter
- Option 2: Meter
- Option 3: Centimeter
- Option 4: Kilometer

3. **Convert the Units**:
- **Decameter**: 1 decameter = 10 meters. This unit is too small for such a long distance.
- **Meter**: 1 meter is a basic unit of length, but it is also too small for the distance between two major cities.
- **Centimeter**: 1 centimeter = 1/100 meters. This is even smaller and not practical for measuring large distances.
- **Kilometer**: 1 kilometer = 1,000 meters. This unit is suitable for measuring long distances.

4. **Choose the Most Appropriate Unit**: Since the distance between Delhi and Mumbai is large, the most appropriate unit to express this distance is kilometers.

5. **Conclusion**: Therefore, the distance between Delhi and Mumbai is usually expressed in kilometers.

### Final Answer:
The distance between Delhi and Mumbai is usually expressed in units of **Kilometer**.
