1, the second hand walks the big grid for 5 seconds, and the angle is 30;
2. The minute hand walks a big grid for 5 minutes, and the angle is also 30;
3. Walk clockwise for one hour at an angle of 30;
4, the hour hand walks one grid, and the minute hand walks one circle, which is 360; The second hand goes 60 times.
The general mathematical clock problem starts from these aspects. As long as you master it, it should be no big problem!
I hope it helps you!
