Did you hear about the math student who walked around a city block by taking?

Answer 1

a square root

Answer 2

The square route, although city blocks are frequently more rectangular.

Answer 3

Yes, I have heard of this math puzzle! The student started at point A on a city block, walked 1 mile north, 1 mile east, and 1 mile south, ending up back at point A. This is possible if the student was walking around the North Pole, where the lines of longitude converge. This scenario takes advantage of the fact that at the North Pole, all lines of longitude are the same length, allowing the student to walk in a square path while technically only walking 3 miles.
