Consider this...suppose you are just over a mile from the SOUTH pole. You walk a mile south - and now you're maybe a hundred feet from the South pole. Then you turn west and start walking...around and around in a tiny 100 foot radius circle centered on the pole. When you've finally clocked up a mile - you turn and head North again...where do you end up?
Well, the answer depends on the exact circumference of the circle that you walked around. Generally, you'll end up someplace very different from your starting point...BUT if that circle is an EXACT sub-multiple of a mile - then you'll end up precisely where you started.
So...the North pole is clearly NOT a unique answer.
Furthermore - the north pole is only ONE answer. My approach reveals an infinite number of possible answers:
1) You could have started ANYWHERE that's at the exact right distance from the pole - so anywhere on that circle will do...an infinite number of starting points will work.
2) Note that ANY exact sub-multiple of a mile will do - so with mathematical precision, there are an infinite number of sub-multiples of a mile - and hence an infinite number of distances from the pole where you could have started.
Truly - the "North Pole" example exhibits very little lateral thinking... if that was your answer then you **FAILED** the Musk test...which (I'm pretty sure) is the whole point here.
The original version of the story is that a hunter walk a mile south, a mile west, shoots a bear, then walks a mile north to return to his starting point. What color was the bear?
Since there are no bears at the south pole - and only polar bears live anywhere near the north pole - then the north pole is the right place and the correct answer is "WHITE!"....but Musk isn't asking *that* question...he's trying to trick people into jumping to a false conclusion without stopping to think about it.
