HOW DID IT HAPPEN???
I think this answer
doesn't work: when you get to the South pole, how do you run West?
Yep. I presume you mean 1 mile north of south pole?
But this answer:
does: for example, any point on the circle (1 + 1/2pi) miles from the South Pole.
There's an infinite number of circles around the South Pole where he could have started.
After going South 1 mile, you're (1/2pi) miles from the Pole,
which allows you to run West 1 mile [1 lap of a 1-mile circumference circle]
and be able to go a mile North to the starting point.
As Martini noted, there is an infinite number of starting distances:
1 + 1/2Npi miles North of the South pole where N is any positive integer.
N is then the number of circular laps in your westerly mile.
e.g. N=5280 - you'd run 5280 laps around a 1-foot circumference circle.
Here's a counter question - why can't N be negative?
i.e. start closer than a mile - you could still do N laps Go to the full post

Had he gotten a help from something else there is infact an infinate possibity of where he started

IF HE WAS TO START 1 MILE NORTH OF THE SOUTH POLE THEN WHEN HE GO TTO THE SOUTH POLE TO GO WEST HE WOULD BE PIVOTING ON ONE FOOT DIRECTLY OVER THE POLE AND SPINNING WITH THE OTHER FOOT FOR ONE MILE AND HE WOULD QUICKLY BE STANDING IN A BIG PUDDLE ON THE SNOW OR ICE BECAUSE HIS SHOE OR BOOT THAT WAS PIVOTING OVER THE SAME SPOT ON THE POLE WHILE TRAVELING WEST WOULD HEAT UP FROM THE CONSTANT FRICTION IN THE SAME SPOT FOR THE ENTIRE MILE...
I DUNNO THE NORTH POLE SOUNDS RIGHT TO ME THO!
I DONT HAVE TIME TO MAKE A DIAGRAM TO BETTER EXPLAIN RIGHT NOW, SORRY
