    Answer:

    25.13 m/s

    Step-by-step explanation:

    Linear velocity = Distance / time

    The distance = Circumference of turbine = 2πr

    Radius, r = 40 m

    Circumference= 2 * π * 40 = 251.327

    The linear velocity is thus :

    Circumference / time

    = 251.327m / 10s

    = 25.13 m/s
