How many degrees does the minute hand turn from 1:15 To 1:55 on the clock? How many degrees does the hour hand turn?

How many degrees does the minute hand turn from 1:15 To 1:55 on the clock? How many degrees does the hour hand turn?

From 1:15 To 1:55 on the clock, the minute hand turned 240 degrees and the hour hand turned 20 degrees

On the clock, from 2:30 to 2:55, how many degrees does the clock turn

It takes 60 minutes to turn a minute hand for 360 degrees, and every minute is 6 degrees
Minute hand turns 60 minutes, hour hand turns 5 minutes; minute hand turns 1 minute, hour hand turns 5 / 60 = 1 / 12 minutes
2: 55-2:30 = 25 minutes
Minutes of clockwise rotation: 25 * (1 / 12) = 25 / 12 = 2 and (1 / 12) minutes
Clockwise rotation angle = (25 / 12) * 6 degree = (25 / 2) ° = 12.5 degree

From 8:15 to 8:55, the clock turns degrees
To calculate the process

According to 60 minutes corresponding to 360 degrees, 15 points to 55 points is 40 points, corresponding to 40 / 60 = x / 360, calculate the X in the above formula is the answer
