Where on the surface of the earth could you travel 1 mile south 1 mile east and one mile north and end up at your starting point?
the North Pole
The first, which most engineers guess correctly, is the North Pole. If you start at the North Pole and go one mile south, then one mile west and finally one mile north, you’ll make a triangular path and end up back at the North Pole, your point of origin.
Where are you on Earth’s surface when you are nowhere?

Where on earth can you walk one mile north?
So your walk of 1 mile West is a complete circle. You then walk 1 mile North, which brings you back to your starting point, (1 + 1/(2pi)) miles from the South Pole. The obvious answer is the North Pole.
How many places are there on the earth where you can walk one mile south one mile east one mile north and end up exactly where you started assume the Earth is a perfect sphere that your compass bearing is constant on each leg of the walk?

How to travel one mile east, one mile north?
To begin, we travel one mile south to point on the circle C (1). Then, we travel east along the circle C (1), and by its construction, we end up exactly where we began.

Is it possible to be one mile north of the South Pole?
One way this is possible is if you are on a line of latitude so close to the South Pole that the entire circle of latitude is exactly one mile around. We will label this circle C (1) for convenience. With this circle in mind, it is possible to figure out a solution. Let us begin the journey from a point exactly one mile north of C (1).
