At 6 o'clock, the minute hand and the hour hand form an angle of 180 degrees, which is divided into five equal parts every hour, and each equal part is 6 degrees. The hour hand walks 6 degrees every minute, and the hour hand walks 6 degrees every 12 minutes. When the minute hand makes an angle of 45 degrees with the hour hand, there are two situations:

1, when the minute hand does not exceed the hour hand. (180-45)/(6-6/12) = 24.55 points =270/ 1 1 points are divided into 45 degrees at 6 o'clock.

2. When the minute hand exceeds the hour hand. (180+45)/(6-6/12) = 40.91min = 450/1min 6: 00,450/1min.
