perplexus.info :: Logic : Burning ropes

Burning ropes (Posted on 2002-03-28)

You have two ropes. You know that each rope takes one hour to burn from one end to the other, but that the burning does not take place at a constant rate (i.e. half the rope may burn in one minute, and the other half will take 59 more minutes to burn).

How would you go about measuring a 45 minute time interval with just these two ropes?
