    Answer;

    Note : Satellite completes one orbit in the same time the earth rotates one about its axis

    circumference of the orbit = 2 * π * 4.23*10⁷ (similar to the earth orbital speed

    The time of earth/orbit traveled = 23.93 hrs,

    Speed of the orbit = (distance) : (time)

    = circumference : time

    = (2 * π * 4.23*10⁷) : 23.93 (1 hr = 3600 sec.)

    = 3085.14 m/s

    The orbital velocity is 3085.14 m/s
