2 km 5 m is equal to

Options

A. `2.05` km
B. 2.5 km
C. 2.005 km
D. 2.0005 km

Answer

To solve the problem of converting 2 kilometers and 5 meters into kilometers, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Units**: We need to convert 5 meters into kilometers. We know that 1 kilometer is equal to 1000 meters.

2. **Convert Meters to Kilometers**:
- Since 1 meter is equal to \( \frac{1}{1000} \) kilometers, we can express this as:
\[ 1 \text{ meter} = 0.001 \text{ kilometers} \]
- Therefore, to convert 5 meters to kilometers, we multiply:
\[ 5 \text{ meters} = 5 \times 0.001 \text{ kilometers} = 0.005 \text{ kilometers} \]

3. **Add the Kilometers**:
- Now, we add the converted kilometers to the original kilometers:
\[ 2 \text{ kilometers} + 0.005 \text{ kilometers} = 2.005 \text{ kilometers} \]

4. **Final Result**:
- Thus, 2 kilometers and 5 meters is equal to:
\[ \boxed{2.005 \text{ kilometers}} \]
