Angle Between Hands of Clock

Formula : H  x 30 degree - M x 5.5 degree.

H - Hour

M - Minute


Eg: The angle between the minute hand and the hour hand of a clock when the time is 4:20 is:

= 4 x 30 - 20 x 5.5

= 120 - 110

=10 degrees.


Find the time in the mirror image.

Formula : if time is more than 11.00 then subtract it from 23.60 else subtract it from 11.60.


Eg: What will be mirror image of Clock Time 3: 40

= 11:60 - 3:40

8:20
