 		 #152147 - you don't need this
Responding to: ???'s previous message
let simply burn the second string from one end from the beginning. At the moment when the first string (being burned from both ends) burns up, you are left with 30 min's worth what remains from the second string. So, simply ignite its other end at this moment (requires to stand by).

Btw., Kai, I like your statistical method very much, even if I think that it still needs a formal proof. Thinking out of the box, that's really clever, although some technicalities might have been involved...

(OK, let's put this down as an another, this time advanced, interview question: given 1M pieces from the 1h string, what is the distribution of timing of burning 750k of them in series?)
