A traveller starts out from the Earth's equator, heading exactly northeast. Undeterred by mountains, oceans and political boundaries, he continues on a northeasterly heading until he can go no further.
Where does he end up?
How far did he go?
How many times did he circumnavigate the earth? (For these purposes, this means travel through 360 degrees of longitude.)
Im still not convinced of the validity of trigonometry / pythagoras
in a curved geometry. Especially since one cannot "flatten" out the earths surface, whereas it can be done for example in the "string around the cylinder" puzzle. (ie cylinder is "flattenable")
However, ive seen this same puzzle on another
site and they offer the same solution as here,
so i guess it may be one of those counter-intuitive situations..
