A satellite takes 93.8 minutes to orbit the earth. If the diameter of the earth is 12740km approximately and the satellite is at a height of 32km above the earth's surface, find the average speed of the satellite in km/h
Working out please

  • Maths -

    C = 2pi*r
    = 2 pi * (12740 + 32) km

    that's the distance traveled in one orbit.

    divide that by 1.563333 hours per orbit, and you get km/hr
