At 1 o'clock the minute hand (red) points to the 12 and the hour hand (blue) points to the 1. (The derivation of θ can be found at Clock Angle Problem Formula.) Angle traced by minute hand in 25 min = (360/60 * 25) = 150 0 Reflex angle = 360 0 - 312 1 2 - 150 0 = 360 0 - 162 1 0 2 = 197 1 0 2 Subject: Clocks - Quantitative Aptitude - Arithmetic Ability Exam Prep: Bank Exams Job Role: Bank PO Send your complaint to our designated agent at: Charles Cohn sufficient detail to permit Varsity Tutors to find and positively identify that content; for example we require 2014-06-09 13:10:25 . With this in mind, we can say that each number represents an angle. At  the minute hand will be one-quarter of the way around the entire dial. Using the 8 hour analog clock from question 1 (an analog clock with 8 evenly spaced numbers on its face, with 8 where 12 normally is), what is the angle between the hands at 1:30? as This activity asks the pupils to cut up the face of Big Ben and measure the angles between the different hands on the clock. 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). There are 120 degrees between the 3 and the 5, where the minute hand is, so the total amount of degrees between the hands is: What is the angle between the clock hands when the clock reads 6:30? Skip to content . What would you like to do? 1) Calculate the Angle between 12 and the Hour hand 10: Since there are 360 degrees in a full circle (clock), and there are 12 hours, each hour represents 360/12 = 30 degrees So our formula is 30(H) So our formula is 30(10) θh = 300 Next, we know how each minute is 1/60 of an hour. Since there are 360 degrees, we can get the angle of the hour hand from 12 o'clock by (((h % 12) + (m / 60)) / 12) * 360. A method to solve such problems is to consider the rate of change of the angle in degrees per minute. In our last example, we have a clock where the hands form a full angle, that is, an angle … m = 6*x. h = angle of the hours hand. (Note: calculate the smaller angle, the one going between the hour and minute hand in a clockwise direction.). Please enter the clock position (at least the hour) or the angle, the other value will be calculated. There must be equations that you can use to do this faster but since I didn't do it that way, I can't round to the nearest second. To find angle B, we have to add to x the number of 30-degree angles from the 12 o'clock position clockwise to the hour hand’s starting position. information contained in your Infringement Notice is accurate, and (c) under penalty of perjury, that you are Last active Feb 17, 2019.

Here, the clock position in hours and minutes and angle in decimal degrees with one decimal place can be converted. Simply enter your time in the format HH:MM and press the button. Thus the hands are  from each other. Star 0 Fork 1 Star Code Revisions 5 Forks 1. Embed Embed this gist in your website. This activity is about Analog clocks and the angles made by the hands of the clock. The total angle the hand covers is 360%, so the angle covered between 3 and 4 should be 360/12 = 30 degrees. Boston College, Bachelor in Arts, Political Science and Government. Since there are , evenly sized, sections of this clock each section has: . When it is 7:00, the hour hand and minute hand of a 12-hour clock form a 150° angle. Angles measuring between 180 and 270 have their terminal sides in Quadrant III, and those measuring between 270 and 360 have their terminal sides in Quadrant IV. Thus there are  between the hour hand and the  numeral. Please be advised that you will be liable for damages (including costs and attorneys’ fees) if you materially Infringement Notice, it will make a good faith attempt to contact the party that made such content available by The angle is typically measured in degrees from the mark of number 12 clockwise. One hour equates to 30 degrees, one minute to half a degree. A analog clock is divided up into 12 sectors, based on the numbers 1–12. At 4:43, though, the angle is not as close to 120 degrees. your copyright is not authorized by law, or by the copyright owner or such owner’s agent; (b) that all of the The line makes angle of 30° from positive y axis Hence it makes angle of (90° + 30°) from positive x axis i.e. Clock Angle Calculator.

Angles measuring exactly 90, 180, 270, and 360 degrees do not have a terminal side that lies in a quadrant, and they’re referred to as quadrantal angles. If creating a picture helps, draw a circle and place 8 at the top where 12 normally is. A description of the nature and exact location of the content that you claim to infringe your copyright, in \ In this wiki we will study common problems about clocks for mental ability. Hand calculations are sometimes easier when you use revolutions but sometimes easier when you use degrees. improve our educational resources. When the clock reads 1:30 the hour hand is halfway in between the 1 and the 2, and the minute hand is on the 4 (at the bottom of the clock). Example: the clock position 9:25 has an angle of 282.5 degrees. m = angle in degrees of the minute hand (clockwise from the top of the clock) The minute had does 360 degrees in 1 hour so it does 6 degrees per minute. With this formula we can find the time when the hands are at right angle by replacing θ with 90° and 270° separately. The measure of the angle between each number is given by . Let this be after x minutes. The minute hand is on the , and there are  between the  and the . Calculator for the angle of direction on the face of a clock.
