The conversation between human and AI assistant.
How many times during a 24-hour period does the minute hand and hour hand of a 12-hour analog clock form an angle of 180 degrees?
Is that a fixed number or does it depend on any other factors?
It's a fixed number. It occurs twice a day because the hour hand moves at a slower pace than the minute hand, and they meet at a 180-degree angle exactly every 12 hours.
