How many degrees clockwise can the minute hand of the clock coincide with the hour hand from the 4 o'clock position?
Assuming that the time of coincidence has passed X minutes, then the equation x = 20 + 5 / 60x is solved to get the angle a = 86400 / 660 = 130.9090 when x = 1200 / 55 = 240 / 11
When the clock rotates 36 ° clockwise from the position of 12:30, what is the time
12：36
If the clock is now 22 o'clock, then what time is it after the minute hand rotates clockwise for 2006?
2006h=83d14h
14h+22h=36h
36h-24h=12h
So it's 12 o'clock sharp
