    Answer:

    16.55m/s

    Explanation:

    If a child rows a rowboat north across a creek at 15 m/s and creek flows east at 7

    m/s. the magnitude of the resultant velocity is gotten using pythagoras theorem as shown

    R² = 15²+7²

    R² = 225+49

    R² =274

    R = √274

    R = 16.55m/s

    Hence the magnitude of the resultant velocity is 16.55m/s
