Question
What will be the angle formed between the hour hand and
minute hand of a clock at 9:23 pm, when take in clockwise direction from the minute hand?Solution
Formula to find the angle between hour hand and minute hand is: Angle= | (11 x minutes - 60 x hours) /2 | Here, minutes= 23, Hours= 9. Angle= | (11 x 23 - 60 x 9) /2 | Angle= | (253 - 540) /2 | = | -287/2 | = 143.5°So, the angle formed between the hour hand and minute hand of a clock at 9:23 pm, when take in clockwise direction from the minute hand is 143.5°.
