    The average speed of the moon around the earth is 1021.74 m/s

    Explanation:

    Radius of moon around earth, r = 3.84 * 10⁸ m

    Circumference of orbit = 2πr = 2 x 3.14 x 3.84 * 10⁸

    Circumference of orbit = 2.41 x 10⁹ m

    Time taken, t = 27.3 days = 27.3 x 24 x 60 x 60 = 2358720 seconds

    We have

    Circumference of orbit = Speed of moon x Time taken

    2.41 x 10⁹ = Speed of moon x 2358720

    Speed of moon = 1021.74 m/s

    The average speed of the moon around the earth is 1021.74 m/s
