Answer» Answer: 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. |
