Let's say you drew a line. It goes on infinitely, in both directions. If you walked from the middle to the left end, and walked from there to the other end, have you walked infinity miles, 1 1/2(infinity) miles, or 3(infinity) miles? If you think that 3infinity = infinity, then the answer is infinity. If you see the whole line as infinity, then you walked 1 1/2(infinity) miles. If you think that each end of the line = infinity, then you walked 3infinity miles. Is there more solutions to this problem? It depends on how you look at it, I only have three solutions (although I'm not sure if they are right.) Is infinity a single value, or does it go on forever? If it goes on forever, how can you reach the end?
