You need to take a trip by car to another town that you have never visited before. Therefore, you are studying a map to determine the shortest route to your destination. Depending on which route you choose, there are five other towns (call them A, B, C, D, E) that you might pass through on the way. The map shows the mileage along each road that directly connects two towns without any intervening towns. These numbers are summarized in the following table, where a dash indicates that there is no road directly connecting these two towns without going through any other towns. Miles between Adjacent Towns Town A B D E Destination Origin 40 60 50 А 10 65 B 10 20 55 40 20 50 D 65 55 10 60 E 40 50 10 80

1. You need to take a trip by car to another town that you have never visited before.
Therefore, you are studying a map to determine the shortest route to your destination.
Depending on which route you choose, there are five other towns (call them A, B, C,
D, E) that you might pass through on the way. The map shows the mileage along each
road that directly connects two towns without any intervening towns. These numbers
are summarized in the following table, where a dash indicates that there is no road
directly connecting these two towns without going through any other towns.
