What is the angle of one revolution?
360° angle
What is the angle covered by the minutes hand in 20 minutes?
For a minute, the hour hand rotates by 30/60 = 1/2 degrees. hence, for 20 minutes it rotates by an angle of 20*1/2 = 10 degrees.
What is the angle at 3 20?
Actually, the answer is 20 degrees. You need to consider the amount of movement of the small hand also. At 3:20, the big hand (minute hand) will have moved by 120 degrees away from the 12 hour mark (20 minutes are equivalent to 120 degrees for the big hand).
How many times hour and minute hand makes an angle of 180 degrees?
Correct answer: Since there are 30 degrees between each number on the clock face, the hour hand is 30 + 15 = 45 degrees away from 12. The minute hand is on 6, which is 180 degrees from 12.
How many times from 4pm to 10pm the hands are at right angles?
Solution. Explanation: Every hour the hands of a clock are at right angles twice i.e. in 6 hours (4 to 10) they would be right angles to each other 12 times.
At what time between 9 and 10 will the hands of a clock be in the straight line but not together?
The hands will be in the same straight line but not together i.e.,in 180 degrees at 180/11 min. past 9. Q: Minutes Hand Clock Puzzle?
At what time between 3pm to 4pm minute hand and hour hand will be opposite to each other?
∴The hour and minute hands overlap each other 180/11 minutes after 3:00.
What is the time between 2 and 3 o clock?
At what time between 2 and 3 o’clock will the hands of a clock be together? Explanation: At 2 o’clock, the hour hand is at 2 and the minute hand is at 12, i.e. they are 10 min spaces apart. To be together, the minute hand must gain 10 minutes over the hour hand.
