Good suggestion! That would work well if the ropes burned consistently, but it’s possible that those 5/12 portions are more/less volatile than the remainders, meaning they could burn for 25 minutes, but also they could burn for 10 minutes, or 50.
Answer context: if you light both ends of one rope, the two flames will always meet each other and fizzle out in exactly 30 minutes.
Key takeaway:
1 flame on a rope = 1 hour
2 flames on a rope = ½ hour
So you may (correctly) think that 3 flames = ⅓ hour. But there’s trick to it. Those 3 flames should always be; 2 on the end, and 1 arbitrarily in the middle.
Doing this will actually cause 1 rope segment with 3 flames to turn into 2 rope segments with 4 flames. Since that middle flame was placed arbitrarily, we can expect one of the segments to burn up before the other. When this happens, we just place a new flame arbitrarily in the middle of the remaining segment, splitting it back into 2.
As long as we keep adding flames so that we always have 2 segments, the total rope will ultimately burn in 20 minutes (⅓ hour).
This is generalizable; to achieve any fraction of 1/x hours, we need to always maintain x-1 segments (min 1). So for ½ hour, we need to maintain 1 segment. For ⅐ hour, we need to maintain 6 segments, etc.
Final answer: 25 minutes can be expressed as ⅙+¼ hours. Therefore we need to burn the first rope such that we always maintain 5 segments. Then once that’s fully burnt, we just burn the second rope such that we always maintain 3 segments.
I don’t care about Karma, but to see a 0 after spending an hour on something means that it will not get seen (when I thought people would enjoy it). So in a way it invalidates my effort, and causes me to reevaluate what people would like to see (and, it seems my content may not be it).
One financial lesson they should teach in school is that most of the things we buy have to be paid for twice.

Not saying I necessarily agree with this sentiment for “everything”, but from a purely monetary point of view, here’s a few example that I assume follow the spirit of this line of thinking:
Cars; you must pay for maintenance & fuels
Homes; you must pay for upkeep & utilities
Computers; electricity costs, and you could even go so far as to say the software you use
