Teaching English to 10-12 years old students?
What do you do with these students (4th-6th grade in priamary school) to get their attention? a) They are too noisy. What can I do to make them to be quiet? (Dont tell me to send them to headmaster) b) To make the lesson interesting? Some fun activities? c) How can I make them love the lesson of English (as a foreign language)? d) What are some basic things they should learn (for instance months, seasons, days, numbers etc.)? Thx in advance!
The minute hand of a clock is 6 inches long. How far does the tip of the minute hand move in 15 minutes?
Length of arc L = Theta * radius, theta = 90 degrees or pi/4 radians (15 minutes), and 150 degrees or 5pi/6 radians (25 minutes) So L = (6 inches * pi/4) = 9.424 inches and L = (6 inches * 5pi/6) = 15.708 inches
How can I teach myself to tell time from a watch with no numbers?
Wow Anonymous - way to not read the question at all. This person knows how to tell time. They are asking how to tell time on a watch with no numbers. Basically you just need to get used to it. You know that if the hand is exactly down then it is 6, if it's pointing to the top its 12, to the right its 3 and to the left is 9. Using these as reference points you can figure out if the hand is more than half way between the 3 and the 6 it is after 4:30 and so on. You can't tell exact time on a watch with no numbers, but you can get to within 1 or 2 minutes. Maybe you could start with a watch that has only 12, 3, 6, and 9 and become comfortable reading the time in between. After that you could get a watch with no numbers at all.
If it is 12 noon at Greenwich, calculate the local time of the places located on the following longitudes: 69°E, 30°W and 12°E?
every 1° is equal to 4 minutes.If it is on west of greenwich median than substract the calculated time from actual time of GMT and if it is on east than add.69°E = 69×4 = 276 minutes i.e 4 hours 36 minutes.time on greewich is 12:00 . so, time on 69°E is12 +4 hr 36 min = 16:36similarly in case of 30°west we have to substract the time i.e12 - 2 hrs = 10:00and for 12°E again add12+48 min = 12:48Hope this was helpful.Thanks for A2AP.STime I followed here is military time i.e 24 hours clock.East or west of longitudes measures from 0° i.e greenwich median line.

How do we calculate the time difference between two countries?
The earth has 360 imaginary lines called longitudes or meridians running vertically between the poles. Each of these longitudes is called a degree. The 0 degree longitude passing through Greenwich, near London, is considered as standard and the time of all other time zones are calculated accordingly. The time difference between each longitude (each degree) is 4 minutes. So if it is 12 noon at Greenwich (0 degree), it would be 12:04 pm at 1 degree meridian and so on. In India, the standard meridian is 82-and-half degree. So the time difference between Greenwich and India is 82.5 x 4, which is 330 minutes (5 hours 30 minutes).
How is standard meridian of India (or any nation) calculated?
Prakash, Thanks for your A2A. In 1878, Sir Sandford Fleming (1827–1915) developed the system of worldwide time zones that we still use today. He proposed that the world be divided into 24 time zones, each spaced 15º (fifteen degrees) of longitude apart (like 24 sections of an orange). He came to this idea because Earth completes a rotation every 24 hours and there are 360º of longitude, so each hour Earth rotates 1/24th of a circle or 15º.As with many new ideas, his solution was not immediately embraced. Railroad companies in the U.S. finally began using Sir Fleming's standard time zones on November 18, 1883. An International Prime Meridian Conference was held in Washington, DC, in 1884 to standardize time around the world and select the Prime Meridian, or the meridian that is designated 0º from which all other longitudes are measured (often referred to as Greenwich Mean Time or GMT, because the place they chose as the Prime Meridian was Greenwich, England). The International Date Line, the imaginary line where travellers change from one date to another, is located at roughly 180º, exactly halfway around the world from Greenwich (conveniently drawn through the Pacific Ocean so no countries are divided into separate days).According to international convention the longitudinal difference between two time meridians should be a multiple of 7.5 degrees, so that time difference is always in half hours or full hours (7.5 deg * 4 min/deg = 30 minutes). To find the time meridian of a country, take the westernmost longitude and the easternmost longitude of that country, take the mean, and find the nearest multiple of 7.5 degree.As India's longitudinal extent is from 68° 7' 53" E to 97° 24' 47" E.Nearest multiple of 7.5° is 82.5°.So 82"30 minutes east has been selected as the Standard Meridian Time of India.USA has 6 time zones at it has very vast area, it is not feasible with only one time zone.
