Rope puzzle…..

Today Linda Michelson Sandler reported that her husband – who is not a FB friend of mine – but should be – has been wondering why I have not posted any more puzzles. You know you have created a problem when people are asking around why you are not posting puzzles 🙂

I had to quickly think of this one. If you know it send me PM.

You are given a bunch of ropes and a few match sticks. What you know about the ropes is that they all burn at very different rates at different segments but each one of them burns off completely in exactly 1 hour (60 minutes).

How can you measure 45 minutes? What is the minimum number of ropes and match sticks you need and how would you do it?
