The radius of the orbit = 42250 km
Speed if it takes 24 hours to revolve around the earth
Therefore, circumference of the orbit = 2*π*42250km = 265571.42 km
Time taken for the orbit = 24 hours
Therefore, speed of the satellite = 11065.4 km.h-1
The satellite orbits the Earth at a speed of 11065.4 kilometers per hour.
