Calculating 25 minutes by burning 2 inconsistently burning 1-hour ropes
Calculating 25 minutes by burning 2 inconsistently burning 1-hour ropes
You are given two ropes and are told that they burn at inconsistent rates, but will always take 1 hour to completely burn up. This means that cutting one of the ropes perfectly in half will not give you two smaller 30-minute ropes.
You are told that you need to approximately calculate 25 minutes by burning these ropes in some fashion.
How do you accomplish this?
Hint: ::: spoiler first ½ of hint I carefully chose approximately instead of precisely ::: ::: spoiler second ½ of hint because to calculate it precisely would require that you ignite an infinite number of flames :::
