There are 4 different roads from city A to city B and 2 different roads from city B to city C. Draw a map of the given situation and determine how many possible routes exist from city A to city C passing through city B.

To find the total number of routes from city A to city C passing through city B, we multiply the number of ways to go from city A to city B (4 roads) by the number of ways to go from city B to city C (2 roads).
Thus, the total number of possible routes is:
possible routes.
