Problem>Hunters go south 50 miles, west 50 miles, shoot bear, go north
	50 miles and are home. Find a location different from the North Pole
	where their home is.

I think this is in one of Martin Gardner's articles:

At some point in the Southern Hemisphere (you know, the Land Down Under ),
going east/west 50 miles means making N ( N = 1, 2, 3, ... ) complete round(s)
around the earth. Just start that 50 miles north of such point.

The place where 50 miles east/west makes N complete rounds can be found:

Let r = 50 / (2 N pi) and R = radius of the earth ( in miles ). Then that
place is at Arccos(r/R) South.
