First, the time zones along the 90th meridian east are, from north to south,...
Longitude measures the angular distance of a place east or west of the meridian at Greenwich, England, or west of the standard meridian of a celestial object, usually expressed in degrees and minutes.
There are 360 degrees. They are numbered 0, 1-179 East, 180, and 1-179 West.360 degrees.On the earth, there is the Greenwich Meridian = 0 deg;1 - 179 East and 1 - 179 West;and 180 deg, much of which forms the International Date Line.
In the Atlantic Ocean, about 300 km east of the Azores.
There can't be too much there, since there's no such longitude as 270 degrees. Longitudes ... both east and west ... range from zero to 180 degrees, max.
No, subtract one hour for each time zone to the West. The sun rises in the East, sets in the West, so it takes longer for the sun to get to the West. The exception would be crossing the International Dateline from East to West.

70W is 180 degrees away from 110E, so if it's noon at 70W, it's midnight at 110E.

If it is 4 a.m. at 15 degrees east, we need to calculate the time difference with 30 degrees west. The Earth is divided into 360 degrees of longitude, with each hour representing 15 degrees. Traveling from 15 degrees east to 30 degrees west is a difference of 45 degrees, which is equivalent to 3 hours. Therefore, if it is 4 a.m. at 15 degrees east, it would be 1 a.m. at 30 degrees west.

To convert decimal degrees east to decimal degrees west, you can subtract the east longitude from 360. For example, if the longitude is 80 degrees east, to convert it to degrees west, you would do: 360 - 80 = 280 degrees west.
The time difference between the east coast and the west coast of the United States is due to their respective positions within different time zones. The Earth is divided into 24 time zones, each roughly 15 degrees of longitude wide. When it is noon on the east coast, it is 9 am on the west coast due to the Earth's rotation.
If the chronometer reads 8 AM Pacific Standard Time at solar noon, it indicates that your location is 120 degrees west longitude. This discrepancy in time suggests that you are 2 hours away from the Pacific Time Zone (120 degrees west longitude corresponds to a 2-hour time difference from Pacific Time).
