Why is time needed to calculate longitude?
Jun 20, 2024 · The relationship between longitude and time is closely linked. As the Earth rotates 360 degrees in 24 hours, each degree of longitude represents a difference of 4 minutes in time. This means that for every 15 degrees of longitude, there is a one-hour time difference.
Apr 16, 2024 · The relationship between longitude and time is that local time varies with longitude due to the Earth’s rotation and position in relation to the Sun. A difference of 15° longitude corresponds to a one-hour difference in local time, or a difference of 4 minutes for each degree of longitude.

Today we are going to learn how to calculate time using Longitudes. We know that our earth is spherical in shape. Therefore, somewhere it will be morning and somewhere it will be afternoon, evening or even night. So, if you are in India and you want to know the time in London or U.S.A., you can easily calculate with the help of longitudes. Remember...
Longitudes and Globe
There are 360 longitudes. Longitudes run from 90° North Pole to 90° South Pole. They are semi-circles. Maximum distance between two longitudes are at the equator. Our earth is spherical (round) in shape which is 360° Earth takes 24 Hours to complete one rotation. It means, we can say that 360° are covered in 24 hours. Therefore, in 1 hour, earth will rotate 360 divided by 24 = 15° So in 1 hour 15 degrees, 2 hours 30 degrees, 3 hours 45 degrees…………..and so on. Now, Let’s calculate in Minutes....
This is the simplest way to calculate time. You just have to remember that there is a time difference of 4 minutes between any two longitudes You will understand better with some solved examples.
Question
If the time at 0° Longitude is 4:00 a.m. What will be the time at a) 8° West and b) 35° West longitudes.
Solution a)
Given is, Time at 0° Longitude = 4.00 a.m. To find is, Time at 8° West Longitude ? First you will see there are how many longitudes between the time given and time asked i.e. from 0 to 8° West Longitude. Between 0° to 8°, there are total 8 longitudes, (1, 2, 3, ..7, 8) We know that between any two longitudes, there is a time difference of 4 minutes. Therefore, time at 8° West longitude will be 4minutes x 8 = 32 minutes. . 8° longitude lies to the left (West) of 0°, so you will subtract...
Solution b)
Given is, Time at 0° Longitude = 4.00 a.m. To find is, Time at 35° West Longitude ? First you will see there are how many longitudes between the time given and time asked i.e. from 0 to 35° West Longitude. Between 0° to 35°, there are total 35 longitudes, (1, 2, 3, ..34, 35) We know that between any two longitudes, there is a time difference of 4 minutes. Therefore, time at 8° West longitude will be 4minutes x 35 = 140 minutes. . 35° longitude lies to the left (West) of 0°, so you will...
GMT is Greenwich Mean Time which lies at 0° Longitude (Prime Meridian) IST is Indian Standard Time which lies at 82° and 30′ E (82 and 1/2 ° East) Now, Suppose the time at GMT ( 0° Longitude) is = 12.00 Noon. you have to find Time at 82° 30′ East Longitude which will lie to the right (East) of 0° Longitude. First you will see there are how many lon...
Question 1.
Calculate the longitude of a place where the local time is 6:00 a.m., when the time is 9:00 p.m. at New Delhi on longitude 77° E Solution) Time given at New Delhi (77° East) is 9:00 a.m. (Local time) To find is the longitude of a place where the local time is 6:00 a.m. Total time difference between New Delhi and of place B is 9:00 p.m. – 6:00 p.m.= 3 hours. We know that between any two longitudes, there is a time difference of 4 minutes. So, 3:00 hours is equal to 180 minutes. 180 divided by...
Question 2.
Calculate the local time at Singapore (104°E) when it is 6:00 p.m. at Greenwich? Solution: Time given at Greenwich (0°) is 6:00 p.m. To find the time at Singapore which is at 104°E. First you will see there are how many longitudes between the time given and time asked i.e. from 0 to 104°E.. Between 0° to 104°E., there are total 104 longitudes, (1, 2, 3, 4, 5..102. 103. 104) We know that between any two longitudes, there is a time difference of 4 minutes. Therefore, time at 104°East lon...
The longitude of a place is its angular distance east or west of the Prime Meridian. It is also measured in degrees. The longitudes vary from 0° to 180° eastward and westward of the Prime Meridian (Fig. 3.3).
Apr 9, 2013 · What determines how long a second, minute, or hour lasts? Learn about the development of the units of time and how they depend on the rotation of the Earth on its axis. Learn how time zones are related to lines of longitude. Published on: April 09, 2013.
Aug 6, 2016 · There are 360 degrees of longitude and the there 24 hours in a day so every 15 degrees of longitude equals one time zone. In theory every 15 degrees change in longitude from line zero in England represents a new time zone or a 1 hour difference. 360/24 = 15 degrees.
