Also, I got the third answer "wrong", since I was thinking of Pythagoras, but applying it to a spherical surface with a circumference of distance stated above, which gives the answer not three miles but slightly less (as that is how far I am from the pole at that time; the question didn't state that I was supposed to go back on the surface:) I got the first answer wrong (due to the fact that I was changing miles to kilometers in my head with a direct substitution of 1 mile = 1 km, which is wrong on so many levels).

You have to allow some license, otherwise it's good. You're standing in the wilderness. You set a marker on the ground. You walk one mile south. You turn and walk one mile east. You turn and walk one mile north and arrive back at your marker. You see a bear. What color is it? Hear’s an old puzzle. You have to allow some license, otherwise it’s good.

I looked at your first comment and wondered if you'd read the third puzzle above at all, but of course, you were well ahead of me - the "just north of the south pole" answer eluded me. very good!
