What is the time difference between each degree of longitude?

The time difference per degree is 4 minutes. (1440 minutes divided by 360). There are 15 degrees of longitude for each hourly time zone, yielding 24 zones times 15 degrees, which also equals 360.


How are the longitude coordinates related to the time zones?

Local mean time, the time used before time zones, which is set to noon when the sun is at its highest point in the sky as seen from your city, is one hour ahead for every 15° of longitude eastward. That equates to four minutes ahead for each degree of longitude east, or four minutes back for each degree of longitude west.


What will be the time on 20 degree longitude if it is 12 noon at greenwich?

Greenwich Mean Time (GMT) is the time at the Prime Meridian (0 degrees longitude). Each degree of longitude corresponds to a time difference of 4 minutes. At 20 degrees east longitude, the time would be 20 degrees × 4 minutes = 80 minutes ahead of GMT. Therefore, if it is 12 noon at Greenwich, the time at 20 degrees longitude would be 1:20 PM.


How many minutes for each degree of longitude does he local time of any place vary from the greenwhich time?

The local time of any place changes by 4 minutes for every degree of longitude that it moves east or west from the Greenwich Meridian.


How is a degree of longitude further subdivided?

A degree of longitude and latitude is further subdivided into minutes and seconds (units of arc, not time).

What is the time of local longitude known as?

The time of local longitude is known as local solar time. It is based on the position of the sun in the sky, with noon occurring when the sun is at its highest point. Local solar time varies depending on a location's longitude, with each degree of longitude corresponding to a time difference of four minutes. This system contrasts with standard time zones, which are often established for convenience and may not align precisely with local solar time.


Each line of longitude is how many degrees apart?

One. Longitude is derived from the Prime Meridian. Values are measured in relation to this Prime Meridian as East or West longitude. If you withdraw this constant, Prime, then values are given in Positive, Zero, and Negative. The distance between degree's of longitude are also not exact from top to bottom. At the equator they are approx. 69 miles wide, as you go toward the poles they become smaller, with an example being at a Latitude of 45 degree's a degree of longitude is approx: 49miles wide. These can also be more specific in Minutes and Seconds. A good reference to obtain a better understanding would be: http://nationalatlas.gov/articles/mapping/a_latlong.html


What latitude and longitude gives us the time?

-- Latitude is not connected with the passage of time. -- The sun crosses 15 degrees of longitude per hour. So if you know your own longitude, somebody else's longitude, and what time it is over at his place, then you can figure out the solar time where you are. Really seems like a lot of effort and hassle, when you could just ask somebody what time it is, or look at your watch.


Is there a relationship between sundial time local time and standard time?

Yes. Standard time is that defined along a particular longitude. Local time is related to the longitude of the place concerned. 24 hours = 360 degree. Therefore 1 degree = 4 minutes. Cities to the east of the Standard time longitude are ahead and vice versa for Cities to the west.


How many minutes are in one degree longitude or latitude?

60 minutes in each degree. The International Date Line is at around +180° longitude. If we start moving to the West from +180° longitude after 6 hours we will reach at +90° longitude position and after 24 hours we will reach at -180° longitude which is nothing but our starting position. In this time (24X60=1440 minutes) our Planet moves 360° in total. Now it is clear to realize that 1° equivalent to 4 minutes.
