One... The North Pole

That is not the correct answer.

If you define 'turn' as 'walking half a mile in westward direction', then anywhere on walkable terrain is possible.

It also depends on your instrument of measurement since you could recalibrate the compass.

Sorry for the dry answers but you didn't define the amount of degrees in the turn. If you walk 30 degrees south, then walk a mile east (turning 60 degrees), and turn another 60 degrees before going north you can do this triangle from anywhere.

When did Jimmy. last have a riddle ?

Didn't think I needed to specify that the turns were 90 degree turns....but they are.... and your answer is incorrect.....in fact it's rather hard to understand what you're even saying. Recalibrate?  

I know the given answer, Mike.

But Mercator fans would. 

No idea what you're saying here.

I'm disappointed in the (lack of) quality of responses here. I'd like to close this thread, but since I don't know how to do that, I'm just going to unfollow it. 

That's the answer.

That was the right decision.

What is the radius of a one mile cIrcle, BTW ?

"Is there anywhere on earth from where you can walk a mile south, turn and walk a mile east, turn again and walk a mile north, and end up exactly where you started? 
If so, how many such points are there?"

That was the original Question for them that remain.

But how do you walk a mile south in the South Pole?

Well, I think that one works. After walking south, you're still in the general area of the North Pole, but not exactly in the northernmost point.

We won't. And no one will.

We're on our own now.

We just have to get some quality posters.

Bishoppy3 was right on the ball, actually.

He knows the answer and did a brilliant illustration.

Which you will appreciate when you guys find out the answer.

I don't get it

I said you will WHEN you know the answer, not before.

Be patient.

You will get it, then.
