wen rope 1 is burnout 30 min has gone ...and so out rope 2 which has 30 min left and then burn that from both ends instantaneouly affter rope 1 is ouit.......even if its not instantanous you would measure approxmatley 45 min plus 5 seconds or so

I am resusciting this problem in a new thread, http://www.physicsforums.com/forumdisplay.php?f=33 because it deserves more discussion. To begin, that the question with 45 mins needs two strings but the same question for 15 minutes needs only one string.
