Too easy, they said. Well try this one on for size:
You have two pieces of rope. Each piece of rope takes an hour to burn (you bought them from a store that told you that, of course). They have different lengths, and each rope has varying widths (so you can't say 'It's been burning for half an hour' if it's burned halfway through).
How can you measure exactly 45 minutes by burning the ropes?
I'll leave you to solve this puzzle on your own- that's right, no internet help for you! I'll know if you cheated; I have spies everywhere...
