# Speed of a satellite

 P: 12 Hi ! "What is the speed of a satellite which is at a height of 320 kn and has a time period of 90 minutes" I've never come across such a question ever before. Is there any formula to solve this problem? or do we have to use S= $d/t$ And what exactly does "time period" mean here? The time taken by the satellite to revolve around the earth once?, or something else? Thanks! ~MoniMini
