Question
What is the angle between the hour hand and minute hand
(when taken in anti-clockwise direction from the minute hand) at 2:30hrs?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 2:30hrs = (2 X 30 + 0.5 X 30) = 60 + 15 = 75⁰ Similarly, the angle made by minute hand at 2:30hrs = 30 X 6= 180⁰ So, the angle between the hour and minute hand = 180⁰ - 75⁰ = 105⁰
