How many times do the hand of a clock overlap in 12 hours?

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.

How many times are the hands of a clock makes 72 in a day?

During each of those revolutions, it makes a 30 degree angle twice — once while advancing away from the hour hand, and once while closing toward the hour hand. So during any 12 hour period, the two hands make an angle of 30 degrees a total of 22 times. That's 44 times per day.


How many times are clock hands at 90 degrees in 6 hours?

If you switch to a rotating coordinate system in which the hour hand stands still, then the minute hand makes only 11 revolutions, and so it is at right angles with the hour hand 22 times.


At what time will the minute hand and hour hand?

How many times are the hands of a clock at right angles in a day 24 hours?

Thus, the two hands form a right angle after every 360/11 minutes. Total number of minutes in a day = 24 × 60 = 1440 minutes. Hence, the two hands will form right angle "44 times" in a day.


How many times in a day are the hands of a clock overlap?

BUT the actual answer is 22. Clock hands overlap at: 12:00, 1:05, 2:10, 3:15, 4:20, 5:25, 6:30, 7:35, 8:40, 9:45, and 10:50 TWICE A DAY (AM and PM). There's no overlap at 11:55 because the hour hand is moving closer toward 12 when the minute hand is at 11.


How many times in 24 hours the hands of a clock are straight?

In 24 hours, the hands coincide or are in opposite direction 44 times a day. (a)if statement is "straight" then answer is = 44.
