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.
