How many times do clock hands overlap between noon and midnight?
How many times do clock hands overlap between noon and midnight?
Sample Answer Let’s see…the hands overlap exactly at noon and midnight, so that’s two right there. They’re not exact, but the hands would also overlap near 1:05, 2:10, 3:15, 4:20, 5:25, 6:30, 7:35, 8:40, 9:45, 10:50 and 11:55 twice each day.
How many times do the hour and minute hand overlap?
The hands of a clock coincide 11 times in every 12 hours (Since between 11 and 1, they coincide only once, i.e., at 12 o’clock). The hands overlap about every 65 minutes, not every 60 minutes. Thus the minute hand and the hour hand coincide 22 times in a day.
At what time between 1 and 2 o’clock are the two hands coincident?
To be together, the minute hand must gain 5 min over the hour hand . 55 min are gained by minute hand in 60 min. Hence, the hands will coincide at 55/11 min past 1 .
At what time between 2 and 3 o’clock will the minute hand and hour hand at difference of 5 min?
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. Now, 55 minutes are gained by it in 60 min….At what time between 2 and 3 o’clock will the hands of a clock be together?
| A) 308 | B) 44 |
|---|---|
| C) 24 | D) 154 |
What is the time when the hour hand and minute hand of a clock coincide between 2 00 pm and 3 00 pm?
Explanation: At 9 o’clock, the hour hand is at 9 and the minutes hand is at 12, i.e., the two hands are 15 min. spaces apart. 55 minutes will be gained in 60 min.
At what time between 9pm to 10pm minute hand and hour hand will coincide?
Explanation: To be together between 9 and 10 o’clock, the minute hand has to gain 45 min. spaces. 55 min.
What is the time between 10 o’clock and 11 o clock?
So, from 10 to 11 the second-hand takes about 84° to give the symmetric from with replacing to the vertical line. So, the time is 10 hr 9 min.
How much degrees does it take by hours hand when minutes hand rotate 180/180 in the same time?
Correct answer: At 1:30 the hour hand is halfway between the 1 and the 2. 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. The two hands form a 180 – 45 = 135 degree angle.
What is the angle covered by the minute 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.
