Taxicab geometry is a special kind of geometry that works on city streets. With it you finally have a chance of finding treasure hidden in the city of Arborville.

Here's what you do: Pick an intersection and ask the computer how far it is to the treasure. The computer tells you the distance using taxicab geometry.

In taxicab geometry the shortest distance between two points is not a straight line, but rather the number of blocks a taxi has to travel along the streets. So, in the street plan of Arborville (shown below), the distance from the blue star to the red star is 4 blocks.


Now that you have looked at the map, it's time to have the computer hide the treasure!
