BrainBashers Puzzles

Puzzle IconYou have two ropes.

Each takes exactly 60 minutes to burn.

They are made of different material so even though they take the same amount of time to burn, they burn at separate rates.

In addition, each rope burns inconsistently.

How do you measure out exactly 45 minutes?
