MIND-BOGGLING HIKER RIDDLE ft Anne Wojcicki

You can also go to any point of latitude that is an integer fraction of a mile and go one mile of that. You go south and travel multiple times along that line of latitude. if it's half a mile then you go round twice. then go north and you are back at the original point.

so you have lines of latitude that is 1 mile, 1/2 mile, 1/3 mile,..., 1/n miles. it will converge to the south pole but never touch the south pole.

so you have an infinite more solutions.
