Prompt
You have two ropes, each of which takes exactly 60 minutes to burn completely. However, the ropes burn unevenly, meaning some parts may burn faster or slower than others. You have no other timing device. How can you measure exactly 60 minutes using these two ropes and matches to light them?

How to grade it

Light one rope at one end. When it has burned completely, 60 minutes have passed.

Answer check: Direct from the premise.
