    Answer:

    18 m/s

    Explanation:

    Given that,

    Speed of river is 8 m/s due South

    From the shore, you see a boat moving South with a speed of 10 m/s. Both boat and river are moving in same direction. The resultant velocity will add up.

    v = 10 m/s + 8 m/s

    v = 18 m/s

    Hence, the rowers are moving with a speed of 18 m/s.
