How many degrees is one minute on a clock?
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..
What angle is 6 o clock?
What angle is 2 o clock?
Correct answer: A analog clock is divided up into 12 sectors, based on the numbers 1–12. One sector represents 30 degrees (360/12 = 30). If the hour hand is directly on the 10, and the minute hand is on the 2, that means there are 4 sectors of 30 degrees between then, thus they are 120 degrees apart (30 * 4 = 120).
What angle is 1 o clock?
30°So the angle between the hands of a clock at 1 o’clock is 30° . Note: It doesn’t matter whether we are talking about 1 am or 1 pm, the answer is exactly the same for both. The angle between the hands at 1 o’clock could also be given as the reflex angle 330°, but we will always give the smaller (acute or obtuse) angle.
How many degrees is 60 minutes?
1 degree can be equal to 60 parts which should be called seconds not minutes. And 60 minutes forms 360 degree .
Why is a degree divided into minutes?
The book states that to be more precise, a degree is divided up into sixty equal parts called minutes, and that each minute is divided into sixty equal parts called seconds. This makes sense since we already know that there are sixty seconds in a minute.
Why An Hour Has 60 Minutes?
The Babylonians made astronomical calculations in the sexagesimal (base 60) system they inherited from the Sumerians, who developed it around 2000 B.C. Although it is unknown why 60 was chosen, it is notably convenient for expressing fractions, since 60 is the smallest number divisible by the first six counting numbers …
Why is there 60 seconds in an hour?
Who decided on these time divisions? THE DIVISION of the hour into 60 minutes and of the minute into 60 seconds comes from the Babylonians who used a sexagesimal (counting in 60s) system for mathematics and astronomy. They derived their number system from the Sumerians who were using it as early as 3500 BC.
Why is a circle 360 degrees and not 100?
The Mesopotamians passed their base-60 numerical system to the ancient Egyptians, who used it to divide a circle into 360 degrees, Mary Blocksma writes in her book Reading the Numbers. The 360-degree circle worked out great: The Egyptians loved perfect triangles, and exactly six of them fit into a circle.
How many degrees make an hour?
15 degrees360 degrees ÷ 24 hours = 15 degrees per hour. Each time zone covers 15 degrees of longitude.
Is a day 12 or 24 hours?
The most common convention starts the civil day at midnight: this is near the time of the lower culmination of the Sun on the central meridian of the time zone. Such a day may be referred to as a calendar day. A day is commonly divided into 24 hours of 60 minutes, with each minute composed of 60 seconds.
How many degrees does the Earth turn in 1 hour?
15The earth turns once on it’s axis in 24 hours. This rotation is a full 360 . So, in one hour, the earth turns 15 . Every four minutes, the earth has turned one degree.
How many degrees does the hour hand move in 1 second?
The hour hand moves 360 degrees / 12 in an hour = 30 degrees. It follows that in a minute it moves 30 degrees / 60 = 1/2 degree. Therefore in a second it moves 1/2 degrees / 60 = 1/120 degree.
How many minutes are in a day?
1440 minutesThere is total 1440 minutes in a day. You can determine it in easy calculation. One hour is consist of 60 minutes. One day is consist of 24 hours.

Is a day really 24 hours?
Day Length On Earth, a solar day is around 24 hours. However, Earth’s orbit is elliptical, meaning it’s not a perfect circle. That means some solar days on Earth are a few minutes longer than 24 hours and some are a few minutes shorter. … On Earth, a sidereal day is almost exactly 23 hours and 56 minutes.
How many degree does an hour hand move in 20 minutes?
10 degreesFor 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.
