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:
first ½ of hint
I carefully chose approximately instead of precisely
second ½ of hint
because to calculate it precisely would require that you ignite an infinite number of flames

Welcome!
Hey everyone. I’m coming from Reddit and I’m new to Lemmy, and wanted to join all of the communities that I was subscribed to on Reddit. I’m noticing that, to my knowledge, there isn’t a Math Riddles community yet on any instance. So I’ve created one.
I have some minor mod experience on Reddit, but this is definitely not something that I expect to be hardcore monitoring. I mainly just wanted to open the community to give us a space to post interesting riddles!
If there’s any Lemmy specific best-practices you’d like to see here, please let me know!
