    Magnitude of the overall velocity = 36.06 m/s

    Explanation:

    30 m/s West in vector form = - (30î) m/s

    20 m/s South in vector form = - (20j) m/s

    The overall velocity = ( - 30î - 20j) m/s

    Magnitude of the velocity (x, y) = √ (x² + y²)

    Magnitude of the velocity = √ ((-30) ² + (-20) ²) = 36.06 m/s
