Mapping it Part 3.

I've spotted a less graphic way of finding the distance and getting a bearing?
http://www.movable-type.co.uk/scripts/latlong.htmland he explains the magic maths behind it.
sphinx is at

29.9753,31.1375 or 29°58′31.1″N 031°08′15.0″E

and Billy is at

51.54229, -3.38149 or 51°32′32.2″N 03°22′53.4″W

giving
Distance: 3711km or 2319.375 mils
Initial bearing: 116°49′07″
Final bearing: 140°09′09″
Midpoint: 42°01′53″N, 016°47′52″E
have a look but the line is a little curvy and google say 2308.22 mils.

this has something to do with maps being flat and the world not, see above link.

pfk out.
