A satellite in a nearly circular orbit is 2000 km above Earth's surface. The radius of Earth is approximately 6400 km. If the satellite completes its orbit in 12 hours, calculate the speed of the satellite in kilometers per hour.(pay attention to the radius of the satellite's path it is not 2000km)

C = 6.28r = 6.28 * 6400 = 40192km = Circumference = total dittance traveled.
V = d / t = 40192km / 12h = 3349.3km/h.
