What is angle between hour and minute hand at 2 15?
Answer: 22.5 degrees. Step-by-step explanation: The angle between any two numbers on the clock is 30°.
What is the angle of 2 20?
But at 20 past two, i.e., at 2 : 20, the hour-hand has moved 20 minutes towards 12. ∴ the angle between the two hands of the clock at twenty past two = 60° – 10° = 50°.
What is the angle between minute hand and hours hand when time is 12.00 am?
Explanation: First note that a clock is a circle made of 360 degrees, and that each number represents an angle and the separation between them is 360/12 = 30. And at 2:00, the minute hand is on the 12 and the hour hand is on the 2. The correct answer is 2 * 30 = 60 degrees.
How many degrees does the minute hand move every hour?
An hour hand moves 1/12 of the clock (if that makes sense) in an hour. A clock is a circle with 360 degrees, so it moves 30 degrees per hour. This means that every minute it moves 30/60 degrees, or half a degree. A minute is sixty seconds.
What is the angle between the hour hand and minute hand in an analog clock?
A method to solve such problems is to consider the rate of change of the angle in degrees per minute. The hour hand of a normal 12-hour analogue clock turns 360° in 12 hours (720 minutes) or 0.5° per minute. The minute hand rotates through 360° in 60 minutes or 6° per minute.
How many revolutions minute hand makes in one hour?
In one hour, the minute hand makes one revolution and the second hand goes round 60 times. This means that, in one hour, the second hand passes over the minute hand 60 – 1 = 59 times and the two are also in line (but with 180 degrees between them) 59 times.
What does hour angle mean?
Hour angle. In astronomy and celestial navigation, the hour angle is one of the coordinates used in the equatorial coordinate system to give the direction of a point on the celestial sphere . The hour angle of a point is the angle between two planes: one containing the Earth’s axis and the zenith (the meridian plane),…
