Analog Clock and Minute Marks Puzzle

AI Thread Summary
The discussion centers on determining the time based on the positions of the minute and hour hands of a 12-hour analog clock. The minute hand is positioned on a minute mark, while the hour hand is two minute marks behind, resulting in a 15-degree separation between the two hands. Each minute mark represents 7.5 degrees, leading to the conclusion that the time is 4:24. Participants express curiosity about the reasoning behind this conclusion and question whether other times could also fit the criteria. The focus remains on the mathematical relationship between the hands and the specific time derived from their positions.

The minute hand of a 12 hour analog clock is situated precisely on a minute mark, while the hour hand is situated exactly 2 minute marks behind the minute hand.

What time is it?

Note: For purposes of the problem, each hour mark is deemed as a valid minute mark.

Well, just rambling here. Each minute mark is 7.5 degrees. So there will be 15 degrees between the two hands. And in conclusion, it will be 4:24
 
Ah beat me to it
 
For the record, how did you do it?
 
i don't get it, why 4.24 could it not be other numbers?
 
Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...
Thread 'My experience as a hostage'
I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
