Well.. It is a very easy question.. The total degrees in a circle are 360. And total number of hours are 12. So we can get the angle going through 1 hour to be 360/12 = 30 degrees.
The Earth rotates at the rate of roughly 15 degrees of longitude per hour.
hour angle is the angle measured from greenwich meridian to the body west or south
The Earth rotates at the rate of roughly 15 degrees of longitude per hour.
There are 24 time zones. Divide 360 degrees longitude by 24 and you get 15 degrees for each one-hour time zone.
Every 15 degrees represent one hour. There are 360 degrees around the Earth. Divide 360 by 15 and you 24 - the number of hours in a day, and the time it takes the Earth to rotate on its axis.
On an analog clock it would be 30 degrees. Each hour is going to be 30 degrees. So at 2 it would be 60 degrees.
At exactly 1 o'clock, the hour hand will be at an angle of 30 degrees, and the minute and second hands will be at an angle of 0 degrees.
60 degrees
Think of the old fashioned analog clock at 1 o'clock. Now think of the angle between the hour hand and the minute hand. Not the little angle but the one that goes all the way from 1 through 6 to 12. That angle is 330 degrees.
It is 22.5 degrees.
Each hour, it rotates through 30 degrees, every twelve hours, it rotates 360 degrees.
The minute hand, which is pointing at 3 is at right angles to 12. But the hour hand is no longer pointing at 12. The hour hand does not stay at 12 from 12:00 to 12:59 and then jump through 30 degrees at 1 o'clock. By 12:15, the hour hand has moved 7.5 degrees (clockwise) so at 12.15 the angle is 90-7.5 = 82.5 degrees.
At 11:20 the hour hand is pointing to 1/3 of an hour after 11, which is 20 degrees before 12. The minute hand is pointing at 120 degrees after 12. So the angle between the two is 120+20 = 140 degrees.
The minute and hour hands form an angle of 60 degrees at 10 o'clock
Assuming the hour hand moves steadily for the entirety of the hour, the angle formed by the hour and minute hand would be 55 degrees.
30 degrees
60 degree angle at 4:12 At 4.00 the angle is 120 degrees. In 12 minutes the minute hand moves 72 degrees while the hour hand moves 6 degrees. So that 120 degree angle reduces by 66 degrees in 12 minutes, and the answer is 54 degrees.
