The minute hand moves 360/60=6 degrees, the hour hand moves112 squares, and moves 6 *112 = 0.5 degrees.

Solution: Obviously, the second hand bisects the angle between the minute hand and the hour hand for the first time after 1 minute.

When setting X minutes, the second hand bisects the angle of the minute hand and the hour hand for the first time, so the angle of the hour hand is 0.5X, the angle of the minute hand is 6X and the angle of the second hand is 360X.

So there are: [6x-0.5x]/2 = 360x-360-0.5x.

Solution: X= 1440/ 1427 (minutes)

Answer: 1440/ 1427 minutes later, the second hand bisected the angle between the minute hand and the hour hand for the first time.

Hope to adopt.
