The angle formed is 4/12 of the total number of degrees in a circle, 360. St. Louis, MO 63105. Solution: Angle traced by hour hand in . Math problem. Since there's 360º / 12 = 30º between hours: + The minute hand points at 4. 101 S. Hanley Rd, Suite 300 If it is 4:00, then the minute hand is pointing towards 12 while the hour hand points towards 4. As you wrote an hour hand elapses 30 degrees for every hour. This problem is known as Clock angle problem where we need to find angle between hands of an analog clock at a given time. Question - 1: The angle between the minute hand and the hour hand of a clock when the time is 4 : 20. Missing absolute value ? = 30(H − M 5)+ M 2 = 30 ( H − M 5) + M 2 degree. there are 2 possibilities . Example: Input: h = 12:00, m = 30.00 Output: 165 degree . an Calculate the angle between the hands of the clock if the time is 3: 25 H = 3 M = 25 Calculate the Angle between 12 and the Hour hand 3: 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(3) θh = 90 12 hours = 360 degrees for hour hand or 30 degrees per hour. Angle between hour and minute hands - formula The angle between the hands of the clock at a particular time is given by: θ = 2 1 (6 0 H − 1 1 M) where, θ is angle between the hour hand and minute hand. At 4:30 the minute hand is at 6 and so it makes an angle of 6*30 = 180 deg from 12. The answer indicates that the hands of a clock will make an angle of 10 between 3 and 4 o’clock at exactly 3:18:2/11 ( 3’ o clock 18 minutes and 2/11 of minutes = 2/11*60 = 10.9 seconds) A few other links to logical reasoning based concept have been given below in the table, candidates can refer to the these for any kind of assistance: Within a clock, just like any circle, there are 360 total degrees. The minute hand on the clock will point at 15 minutes, allowing us to calculate it's position on the circle. For Example: Given Input: h = 6:00, m = 60.00; Output: 180 degree Send your complaint to our designated agent at: Charles Cohn 180º . With this in mind, we can say that each number represents an angle. Since there are 12 hours on the clock, each hour mark is 30 degrees. © 2007-2021 All Rights Reserved, GMAT Courses & Classes in San Francisco-Bay Area, LSAT Courses & Classes in San Francisco-Bay Area, GRE Courses & Classes in San Francisco-Bay Area. 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. 10 minutes is 1/6 of an hour so the hour hand has also moved 1/6 of the distance between the 3 and the 4, which adds 5° (1/6 of 30°). sufficient detail to permit Varsity Tutors to find and positively identify that content; for example we require link to the specific question (not just the name of the question) that contains the content and a description of On the other hand, if it indicates 7.45, when the correct time is 8, … The hour hand advances .5 degrees.

When minute hand is behind the hour hand, the angle between the two hands at M minutes past H o’clock. 40 min. To calculate the times necessary for such questions, we need the work out the rate of change of the angle that each hand is rotating. Within a clock, just like any circle, there are 360 total degrees. Notice that the question asks for 'times'. What is the measure of the angle formed between the hour hand and the minute hand? Share the knowledge! A clock is a circle, and a circle always contains 360 degrees. of hours. Create a fraction out of these two quantities to use later as a conversion rate: Between the and there are minutes, so multiply this by the conversion rate to solve for the number of degrees: What is the measure of the smaller angle formed by the hands of an analog watch if the hour hand is on the 10 and the minute hand is on the 2? As the clock is divided into 12 sections, the distance between each number is equivalent to 30° (360/12). If you believe that content available by means of the Website (as defined in our Terms of Service) infringes one Add Your Comment (use Q&A for new questions) B I Format Insert Math? To find the degrees, simply divide the total number of degrees in a circle by 12 to find the degrees between each consecutive number, and then multiply that number by 2.5 because you have half the distance to the 4, and the the full distance to the 5 and the full distance to the 6. 5:15? C. 155º. 1 Division = 30 0. Step 1: Input time in number format. Within an clock, there are 60 total minutes. So if the input is like hour = 12 and min := 30, then the result will be 165°. 8. 7. Formulas for Clock 1. The distance between the 2 and the 3 on the clock is 30°. (A) 100 0 (B) 80 0 (C) 120 0 (D) 200 0. The hour hand is in #3 [which is actually 15 minutes.] Angle 2 = 60°. University of California-Berkeley, Bachelor in Arts, Cellular and Molecular Biology. I understand this working all the way up until the '2n-1' part, where n is a positive integer. Write a program to determine the angle between the hands of a clock. If Varsity Tutors takes action in response to ø = 30h – 11/2 m -----when minute hand is in first 1/2 (between 12 to 6) 54 = 30 × 7 – 11/2 m. 11/2 m = 156. m = 28.36 min = 28 4/11 min = 21.8 s. at 7 hr 28 4/11 min. $${\text{192}}{\frac{1}{2}^ \circ }$$ C. 195º.
