**MathMate**, Thursday, November 11, 2010 at 6:09pmDid you both start at the same time?

Did he cross the streets diagonally?

Are you located near the North Pole, in which case it is preferable to go north, THEN east.

**MathMate**, Thursday, November 11, 2010 at 6:11pm"preferable" meaning that the distance is shorter.

**MathMate**, Thursday, November 11, 2010 at 8:25pmHere's my explanation about the north pole:

If the streets are in the northern hemisphere (such as in the US and Canada), the distance between two longitudes is shorter as we go further north.

Therefore, if you go east 6 blocks, and then north 8 blocks, the distance is longer than if you go north 8 blocks, and then east 6 blocks, because the distance between the same two longitudes (the 6 blocks) is shorter further north.

The further north you go, the greater is the difference. In the limit, at or near the north pole, the difference is considerable.
