Latitude and Longitude II

Performance Objective

The student should be able to:

• Calculation of distances using lines of latitude
• Calculation of local time and longitude
• International Dateline - Time and Time Zones

Calculation of distances using lines of latitude

The distance between one line of the latitude and another is 111km
Two points lying North or South of the equator are subtracted to get the latitude difference.

Example: Calculate the appropriate distance in a straight line between Tama (lat 60N) and London (lat 520 N)
Solution: Latitude difference = 520 – 60 = 460
Average distance = 111km
460 = 46 x 111km = 5, 106km
