1 hr = 60 min.
8 hr = 60*8 = 480.
30 min = 480+30 = 510 hr.
Angle traced by hour hand = 510 hr/2 = 255.
Angle traced by min hand = 360/60*30 = 180.
= 255-180 = 75.
8 hr = 60*8 = 480.
30 min = 480+30 = 510 hr.
Angle traced by hour hand = 510 hr/2 = 255.
Angle traced by min hand = 360/60*30 = 180.
= 255-180 = 75.
