 3. The direct path to a town is always the shortest, i.e. going directly from town A to town C is faster than going from town A to town B and then town C

+**Method 1: Brute Force**
+
+By checking every single possibility and calculating the distance of each route, the shortest path can be determined. However, this strategy does not work for a large number of towns because as **n**, the number of towns, increases, on the first turn, (starting at any town) there are n-1 towns to choose from, then on the second turn there are n-2 choices and so on until there is only one option left which is to return to the starting town. This means that there are `(n - 1)! / 2` total possibilities accounting for duplicates.
