Find the angle between the hour hand and the minute hand of a clock when the time is 3.25 |
|||||||
Answer: Option A Explanation: At 3 O'clock, Minute hand is at 12 while the Hour hand is at 3. Again the minute hand has to sweep through ( 30 x 5 ) i.e., 150° for reaching the figure 5 to show 25 mins. Simultaneously the Hour hand will also rotate for 25 mins. Thus starting from the mark, 3 the hour hand will cover an angle = (25 x 30) / 60 = 12.5° Hence, Angle between Hour and the Minute hand = ( 60 - 12.5 ) = 47.5° |
