    Answer: linear velocity = 169,745.2mi/hr

    Explanation:

    Given: radius of orbit = 2,600,000mi

    Time taken for orbit = 4.01 days = 4.01 * 24 hrs = 96.24hrs

    Linear velocity = distance travelled/time

    distance travelled = circumference of orbit = 2πr

    = 2π * 2,600,000mi

    = 16336281.8mi

    Linear velocity = 16336281.8 / 96.24hrs

    = 169745.2mi/hr
