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?

hm.. interesting.. but from the naked eye it's hard to see that half the rope is burnt... then you have to take into account the other half of the rope that's left over too...
