    Answer: 13. 99 seconds

    Step-by-step explanation:

    The formula to find how long it will take an object to rotate through 6.9 revolutions at an angular velocity is given as:

    t = 2π x number of revolutions / angular velocity

    Therefore:

    t = 2π x 6.9 / 3.1

    t = 2 x 3.142 x 6.9 / 3.1

    t = 43.3596/3.1

    t = 13. 98696774194

    to the nearest tenth

    t = 13. 99s
