How many minutes after 3 00 pm will the minute hand the clock overtakes the hour hand?
Now, 12 hrs 5 min i.e. 145/12 hrs of this clock = 12 hours of correct clock. So, 29 hours of this clock is (29×12×12)/145 = 144/5 = 28 hours 48 minutes. So, the time is 12 minutes before 3 pm. Example 8: The minute hand of a clock overtakes the hour hand at intervals of 65 minutes of correct time.
