Want this question answered?
If she started from the south pole, then she'll wind up 4 miles from her starting point after this series of maneuvers. If she started on or near the equator, then the final distance is roughly 6.4 miles.
The obvious answer is 5 miles. The not-so-obvious part is it depends on where he is when he starts. If he is on the equator, he is five miles from his point of origin. If his starting point was the south pole, and he drives five miles north, then west, then south, he will arrive back at his starting point. Before you disagree, consider that he is driving on a sphere not a flat plain.
25 miles
You can start near the South Pole - 3 miles North of any point on a latitude that encircles the earth an integer number of times in 3 miles; or you can start at the North Pole.
25 miles.

So this uses pythagoras theorem. x = sqrt15 + sqrt 7. So he was 16.55 miles from starting point
