    Answer:

    The woman’s average velocity during the trip is 36.2 miles/hour.

    Explanation:

    Velocity can be define as the displacement of an object per time. It is a vector quantity, and measured in m/s.

    i.e velocity = \frac{displacement}{time}

    From the given question,

    Displacement = \sqrt{200^{2} + 375^{2} }

                           = \sqrt{40000+140625}

                           = \sqrt{180625}

                           = 425

    The displacement of woman is 425 miles.

    velocity = \frac{425}{11.75}

                 = 36.1702 miles/hour

    The woman’s average velocity during the trip is 36.2 miles/hour.
