When both ends of the second rope meet, it'll be another 15 minutes. This adds up to 45 minutes, I think. Unless I'm horribly missing something.
That sounds right. I was on the right track of burning both ends of the first rope for 30 minutes but couldn't get the 15 second part...I ventured down the blind alley of trying to light the second rope in four places...but it only works when you light the ends I guess.
