Mo Liu Stuff: Puzzle part 3

Man. I had such a busy day at the office today. So glad the day is over. Anyway, since I have no brain power left, here's a puzzle that you guys can solve for me!! Good luck!  :) 


Burning rope

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?
