    Answer. 12 km/hr and 2 m are scalar quantities.

    Explanation

    Scalar quantities are those quantities which only have magnitude but no direction, for example: speed, time, mass etc.

    Vector quantities are the quantities which have both magnitude and direction, for example : acceleration, momentum etc.

    5 m northeast and 2 m north are vector quantities telling us magnitude and direction both that is 5 m in north east direction and 2 m in north direction.

    12 km/hr and 2 m are scalar quantities telling us only speed and distance respectively without specific directions.
