Hello student,
The angle traced by hour hand in 12 hrs is 360 degree.
Angle traced by the hour hand in 7 h 20 min, i.e., 322h=(12360×322)degree=220degree
Also, Angle traced by the minute hand in 60 min=360degree
Angle traced by the minute hand in 20 min=(60360×20)degree=120degree
Hence, Required angle between the two hands= 220degree−120degree= 100 degree
