Just a little puzzle my maths teacher gave me... it took me like a day and a half... just wanted to see if anyone could get it.
You have a box of matches and 2 pieces of rope (different lengths). Each rope burns for exactly one hour, but the ropes don't burn at a uniform rate (i.e. it won't have burnt exactly half of its length in half an hour etc)
How do you time out 30 mins exactly?
