Question
What is the angle between the hour hand and minute hand
at 9:28hrs, when taken in clockwise direction from the minute hand?Solution
The logic followed here is as follows: Hour hand makes an angle of 30⁰ in one hour and an angle of 0.5⁰ in one minute. Similarly, minute hand makes an angle of 6⁰ in one minute. So, angle made by hour hand at 9:28hrs = (9 X 30 + 0.5 X 28) = 270 + 14 = 284⁰ Similarly, angle made by minute hand at 9:28hrs = 28 X 6 0 = 168⁰ So, the angle between minute hand and hour hand= 284⁰ - 168⁰ = 116⁰
