Egyszer volt egy kiss hangyat, egyszer nem volt. ;P

Once there was a kiss ants, not once was

Not sure if it's Google's Hungarian translator that's broken, or your Hungarian. :laugh:

If the arrow doesn't get him, the bowl of petunias probably will. :-D

I missed an auto correct, kis not kiss. Once there was a little mouse, once there wasn't. Every Hungarian folk tale starts this way.

So, that's still younger than @OriginalGriff then.

Yes. The ant does not even need to move. Just stay there. Eventually, destination pole will touch the origin pole due to stretching and Earth being spherical (almost). At that point, just switch lanes. :cool:

No, I only feel that old...

Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

SO, each second the ant moves 1cm closer to his goal, which moves approx 50cm further away from him in the same second.(actually, I think in the first second it move 99.5cm away). So, no, he's never going to reach it.

Truth, James

The problem did not specify that the ant is immortal. If it would take 8.547e+35 years then the answer is clearly no, the ant will not reach the other end. Ants don't generally live that long. ;P

I would have thought by this time that version of the puzzle would have involved nano-bots. The first time it was trains; then cars; then people ...

The ant will reach the end -- the part of the whole path he covers in a second is 0.01 / (1 + t), where t is time in seconds (the covered part doesn't decrease since the line extends uniformly). So the total part he has covered up to the time t is 0.01 * ln(1 + t), meaning he crosses whole path in exp(100) - 1 seconds (approx. 10^36 years).

speed of rope at distance x from centre is x/(t+1) (ant starts at x=-50, t=0) speed of ant is x/(t+1)+1 = dx/dt x=c(t+1)+(t+1)log(t+1) so -50=c ant arrives: 50=-50(t+1)+(t+1)log(t+1) let u=t+1 50(u+1)=u log u if u=exp(50), u log u = 50.u which is near enough

I could assure you that you act younger than I am now and then. And that's actually a good thing. :-D
