Final answer:
The paths and their distances based on the map are provided.
Step-by-step explanation:
The paths and their distances, based on the map, are as follows:
1) b -> e -> d = 13 blocks
2) b -> e = 10 blocks
3) d -> e = 17 blocks
4) b = 8 blocks
5) d -> b = 14 blocks
6) a (not used)
7) b (not used)
8) b -> e -> d = 13 blocks
9) b -> e = 10 blocks
10) d -> e = 17 blocks
