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.)
Well, actually, I got conflicting results from a quick Google search. What's the circumference of the earth? The consensus seems to be somewhere in the neighborhood of 24,000 miles, but that's not very precise.
Missing a bit of info...
