Key Points
Express each hand’s angle from 12 o’clock:
Minute hand speed: 6° per minute.
Hour hand speed: 0.5° per minute, with a 60° head start at 2:00.
Set up the equation for coincidence:
Let t be the number of minutes after 2:00. We want the minute hand’s angle to equal the hour hand’s angle:
6t = 60 + 0.5t
Simplifying:
6t − 0.5t = 60 → 5.5t = 60 → t = 60 / 5.5 = 120 / 11 = 10 10⁄11 minutes
Therefore, the hands coincide at 10 10⁄11 minutes past 2,
Hence Correct answer is Option 4.
