Question
![**Solve the Problem**
Suppose there are 8 roads connecting town A to town B and 4 roads connecting town B to town C. In how many ways can a person travel from A to C via B?
- ○ 32 ways
- ○ 64 ways
- ○ 12 ways
- ○ 16 ways
**Explanation:**
To determine the number of ways a person can travel from town A to town C via town B, we need to consider the separate routes between each segment:
1. **From A to B:** There are 8 roads available.
2. **From B to C:** There are 4 roads available.
To find the total number of ways to travel from A to C via B, multiply the number of ways for each segment:
\[ \text{Total ways} = 8 \times 4 = 32 \]
Therefore, the correct answer is 32 ways.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7c5fa014-da02-4c57-a781-fd58c7d971af%2F2efed01d-3a1d-4d83-a66b-9ac63ed68b1b%2Fu8d9rqg_processed.jpeg&w=3840&q=75)
