Worked examples


How to find the co-ordinates of place X in degrees and minutes: 1 Find place X on the map. 2 Place your ruler horizontally across the map passing through X. Read off the latitude. The latitude of X is 18º50'S.


3 Place your ruler vertically across the map passing through X. Read off the longitude. The longitude of X is 119º32'W. You estimate the 32' because the line falls just after 30'.
