Question 992234
.
The satellite flies at the altitude of  (approximately)  100 and more kilometers over the earth surface,  but we will neglect it comparing with the Earth radius of  6400 km. 


      (Actually,  the elementary school Physics allows to calculate the altitude of the orbit if you know the period. 

      At least in my school ears it was so :-).

      But it looks like you don't know this Physics.  Therefore,  I will neglect these details and will assume that the radius of the orbit is  6400 km). 


Then the satellite runs the length of the orbit  {{{2*pi*R}}} = 2*3.14*6400 km  in  92.69 minutes.


Can you now calculate the speed? 


You need simply to divide the distance by the time.


Good luck!
