Diesel Posted August 19, 2005 Posted August 19, 2005 There are 2 pieces of rope. The length and width of the two pieces are not neccessarily the same. Both pieces are inconsistent in width (ex. the middle may be thicker than the ends). Each piece of rope take exactly 1 hour to burn. By burning both pieces of rope, how do you measure 45 minutes of time? Hint: Since the ropes are of inconsistent width, burning half of a rope does not mean that 1/2 hour has passed. Quote

neodammer Posted August 20, 2005 Posted August 20, 2005 I didnt catch if they weighed the same but weighing them at the beginning etc.. and the weighting how much was burned may work. Quote Enzin Research and Development
Joe Mamma Posted August 20, 2005 Posted August 20, 2005 Btw' date=' has anyone entered the google code jam contest?[/quote'] I wish someone might have mentioned this BEFORE the registration ended!!!! :mad: Quote Joe Mamma Amendment 4: The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

Joe Mamma Posted August 20, 2005 Posted August 20, 2005 oh yeah. . . Ignite both ends of Rope1, Ignite one end of Rope2. When Rope1 is exhausted (thirty minutes), Ignite other end of Rope2 (now a thirty minute rope) which will exhaust now in 15 minutes.

Diesel Posted August 21, 2005 Author Posted August 21, 2005 Nailed it. Yeh, the google code jam contest is pretty cool...but I'm assuming most people entering have a library of problems that they reference during the contest. My library is only about a dozen problems right now, so I'll be working on raw coding power. So I'm expecting to get my *** handed to me. Quote
