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?
That's interesting. Another question, can analog clocks be used for any special purposes?
Yes, actually, analog clocks are used in aviation and shipping to help them navigate and calculate speed and distance. They are also used in some schools to help students learn to tell time.
