What will be the time at a place located at 30 degree west longitude when its 12 noon at Greenwich?
30 ×4 = 120 minutes. 120÷60= 2 hrs. This being to the west is 2 hrs from 12noon on Greenwich. 12- 2=10am.
What will be the time at 30 E if the time at Greenwich is 12 00 noon?
12- 2=10am. It would be the local time on 30 Degrees Longitude. 0 degree and 12 Degrees East is 12 Degrees. 12×4=48 minutes.
How do you calculate local time using longitude?
Each degree is divided into minutes and minutes into seconds. The Earth takes 24 hours to complete one rotation or to cover 360° of longitudes. This means that the Earth covers 15° of longitudes every hour. One degree of longitude takes 4 minutes (1 hour = 60 minutes, divided by 15° per hour = 4 minutes per longitude).
When the time is 12 noon at 0 degree longitude the time at 60 degree longitude will be?
The difference in the “longitudinal stretch” with “known reference” = 60°E -30°W = 90° Time that is taken to “travel longitudinal degree” = 4 minutes. Time taken for 90° = 90 * 4 = 360 minutes = 6 hours. Therefore, if it is 12 noon at 60°E longitude, then time at 30°W longitude is 6.00 AM.
When the time is 12 noon at 0 degree longitude the time of 75 degree longitude will be?
12 Noon at Greenwich means 69 deg east will be 12 + 4 hr 36 min (276 min) = 4:36 pm. 30 deg means 30*4=120 min, West means time will be subtracted.
How do you calculate longitude and time?
Why is it 5.30 pm in India when it is 12.00 noon in London?
This is because the Earth rotates 360 degrees in 24 hours, 1 degree in 4 minutes. The standard meridian of India is 82 degree 30E, and that of London is 0 degree. So when it is 12 noon in London, it is 5.30 pm in India.
How is longitude time calculated?
What is the time at 45 degrees east?
Dividing 360 degrees by 24 hours equals 15 degrees per hour. Time gets later as you go east. So 45 degrees east is 30 degrees east of 15 degrees or 2 hours later. This means the time would 11:00 am at 45 degrees east. Now the hard part.
What is the difference between EST and West hours?
Simply mouse over the colored hour-tiles and glance at the hours selected by the column… and done! EST stands for Eastern Standard Time. WEST is known as Western European Summer Time. WEST is 5 hours ahead of EST. So, when it is
How to convert EST to west and vice versa?
This time zone converter lets you visually and very quickly convert EST to WEST and vice-versa. Simply mouse over the colored hour-tiles and glance at the hours selected by the column… and done! EST stands for Eastern Standard Time. WEST is known as Western European Summer Time. WEST is 5 hours ahead of EST.
How far apart are the two longitudes on the Earth?
There are 360 degrees of longitude around the earth so with every 24-hour rotation of the earth that is a rate of 15 degrees per hour. Your two longitudes are 30 degrees apart so they will be two hours apart. With the earth rotating from West to East, this makes the time at 45 East 2 hours ahead of that at 15 degrees East.
