Explanation / Answer
Solution:
Initially you and Larry Longway are at (0, 0).
Going north for three blocks puts you at (0, 3),
Now,
Turning right and going five blocks puts you at (5, 3),
again
turning right (and, hence, facing south) and going three blocks puts you at (5, 0),
again
turning right (and, hence, facing west) and going west five blocks puts you back at (0, 0),
again
turning right (and, hence, facing north) and going straight for three blocks puts you at (0, 3),
Now this time
turning left (and, hence, facing west) and going straight for a block puts you at (-1, 3),
again
turning right (and, hence, facing north) and going straight for four blocks puts you at (-1, 7),
again
turning left (and, hence, facing west) and going straight for two blocks puts you at (-3, 7),
again
turning left (and, hence, facing south) and going straight for one block puts you at (-3, 6),
again
turning left (and, hence, facing west) and walking straight five blocks puts you at (-8, 6).
Therefore,
you should walk eight blocks east and 6 blocks south to return to the original spot.
