The distance between city A and city B is 217.352 km. A man travelling from city A to city B covers a distance of 108.178 km. How much more distance he has to cover?

Options

A. 111.226km
B. 109.174 km
C. 109.147 km
D. 325.53km

Answer

To find out how much more distance the man has to cover from city A to city B, we will subtract the distance he has already covered from the total distance between the two cities.

### Step-by-Step Solution:

1. **Identify the total distance between city A and city B**:
- The total distance is given as 217.352 km.

2. **Identify the distance already covered by the man**:
- The distance covered is given as 108.178 km.

3. **Set up the subtraction**:
- We need to calculate the remaining distance by subtracting the distance covered from the total distance.
- This can be expressed as:
\[ \text{Remaining Distance} = \text{Total Distance} - \text{Distance Covered} \]
- Substituting the values:
\[ \text{Remaining Distance} = 217.352 \, \text{km} - 108.178 \, \text{km} \]

4. **Perform the subtraction**:
- Align the numbers by their decimal points:
```
217.352
- 108.178
___________
```
- Start subtracting from the rightmost digit:
- In the thousandths place: 2 - 8 (we need to borrow)
- In the hundredths place: 5 - 7 (we need to borrow)
- In the tenths place: 3 - 1
- In the units place: 7 - 0
- In the tens place: 1 - 0
- In the hundreds place: 2 - 1

After performing the subtraction, we get:
\[ 109.174 \, \text{km} \]

5. **Conclusion**:
- The man has 109.174 km more to cover to reach city B.

### Final Answer:
The man has to cover **109.174 km** more.
