Math Riddles
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 :::
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!
