do we assume the earth to have a radius of 4000 or some other number?
just read it in there at the end :)
add earths radius and the satellites elevation to get a total radius in order to calculate a distance
once you know the distance, speed = distance/units of time

the distance around any circle is the circunference; or 2pi * radius
okay so then you would get 48066.37 as S right?
i got know idea, id have to actually calculator it :)
