Latitude
and Longitude:
Latitude is distance, measured in degrees, north or south of the
Equator. Longitude is distance, measured in degrees, east or west of any fixed
meridian. The meridian passing through Greenwich is numbered 0O. On a globe the
meridians are numbered from 0O to 180O E (East) or W (West). At the equator the
degrees are 69 to 70 miles apart (25000÷360). Since earth completes one
rotation on its axis in 24 hours, 360 meridians pass under the Sun in that time.
Therefore, 1 degree passes under the Sun every 4 minutes.
