Answer 2

Calculating the Number of Possible Routes

To calculate the number of possible routes from city A to city C via city B, we can use the principle of multiplication. Since there are three roads from A to B and four roads from B to C, we can multiply the number of roads from A to B by the number of roads from B to C to find the total number of possible routes.

Number of routes from A to B: 3 roads Number of routes from B to C: 4 roads

Calculation

To find the total number of possible routes, we multiply the number of routes from A to B by the number of routes from B to C:

3 (routes from A to B) * 4 (routes from B to C) = 12 possible routes

Therefore, there are 12 possible ways to travel from city A to city C via city B.
