I have a question to the following excercise that I have from school.

How big is the delay of a package if it gets send via satelite (~35km above earth)?

I assume I need to calculate this one. However I have no other values so I don't really know if this really can be calculated?

What you need is the distance to be covered and the speed of the signal.

The distance of an arbitrary point on the globe to a point above the equator can be calculated by the cosine rule. The speed of the signal - well, you've probably got that.

btw: geostationary orbit is 35,786 km above the equator, so it's more like ~36,000 km. 35 km is well within the atmosphere, much too low for a satellite (about 50% higher than the normal flight altitude of an SR-71 and somewhat below Baumgartner's and Eustace's stratosphere 'space' dives).
