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 5:20 is:
= 5 x 30 - 20 x 5.5
= 150 - 110
=40 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 8: 20
= 11:60 - 8:20
= 3:40
