PROBLEM 2:

due September 01, 2000

You are given two different lengths of rope.

Facts
• Light one end and either rope will burn up in exactly 1 hour.
• The density of each rope varies in an unpredictable way. So the speed/rate that each rope burns varies unpredictably over its length.

Question:     How can you use these two ropes to determine when 45 minutes have elapsed? (You may use as many matches as you need.)

Solutions, questions and/or comments should be directed to Judy Downey or Griff Elder
