As I said, I need as much data as possible. I figured people who did it once wouldn't do it twice.

Homework Help / Math Survey« on: February 09, 2009, 12:45:50 AM »
I'm collecting some data for school and need data from as many people as possible. Thanks!
Who can solve this problem in one try without looking at the answer?: There are two lengths of rope. Each one can burn in exactly one hour. They are not necessarily of the same length or width as each other. They also are not of uniform width (may be wider in middle than on the end), thus burning half of the rope is not necessarily 1/2 hour. By burning the ropes, how do you measure exactly 45 minutes worth of time? Be honest! And be sure to leave a post saying whether or not you get it on the first try! The answer can be found at http://mindcipher.com/puzzle/41-burning-rope Thanks for your help! 3
