To find the number of routes from Bristol to Carlisle, we need to multiply the number of routes from Bristol to Birmingham, Birmingham to Sheffield, and Sheffield to Carlisle.
Number of routes from Bristol to Birmingham = 4
Number of routes from Birmingham to Sheffield = 3
Number of routes from Sheffield to Carlisle = 2
Let's calculate the total number of routes from Bristol to Carlisle.
1. Number of routes from Bristol to Birmingham:
- The motorist knows four different routes from Bristol to Birmingham.
2. Number of routes from Birmingham to Sheffield:
- The motorist knows three different routes from Birmingham to Sheffield.
3. Number of routes from Sheffield to Carlisle:
- The motorist knows two different routes from Sheffield to Carlisle.
Now, let's multiply these numbers together to find the total number of routes from Bristol to Carlisle:
Total number of routes = Number of routes from Bristol to Birmingham * Number of routes from Birmingham to Sheffield * Number of routes from Sheffield to Carlisle
= 4 * 3 * 2
= 24
Therefore, the motorist knows 24 different routes from Bristol to Carlisle.
