Answer

To solve the problem of how far a man can travel in 5 hours if he covers 10.2 km in 3 hours, we can follow these steps:

### Step-by-Step Solution:

1. **Determine the distance covered in 3 hours:**
The man covers a distance of 10.2 km in 3 hours.

2. **Calculate the distance covered in 1 hour:**
To find out how much distance he covers in one hour, we divide the total distance by the total time:
\[ \text{Distance in 1 hour} = \frac{10.2 \text{ km}}{3 \text{ hours}} = 3.4 \text{ km/hour} \]

3. **Calculate the distance covered in 5 hours:**
Now that we know the distance covered in one hour, we can find out how far he travels in 5 hours by multiplying the distance covered in one hour by 5:
\[ \text{Distance in 5 hours} = 3.4 \text{ km/hour} \times 5 \text{ hours} = 17 \text{ km} \]

4. **Conclusion:**
Therefore, the distance covered by him in 5 hours is **17 km**.

### Final Answer:
The correct option is **D) 17 km**.
