Kurose-Ross 3rd edition chapter 1 problem 18

Question

Suppose there is 10Mbps microwave link between a geostationary satellite and its base station on earth. Every minute the satellite takes a digital photo and send to the station.Assume a propagation speed of 2.4*10⁸ m/s. What is the propagation delay of the link ?

Answer 1

https://en.m.wikipedia.org/wiki/Geostationary_orbit

Propagation Delay= Distance / speed 

                            =35786km / 2.4 *10^8 m/s 

                            =149.1 ms
