    Answer:

    A. 25km

    B. 15km

    Explanation:

    In this problem, we are expected to solve for the total distance covered by the person, and the person’s displacement.

    a) what is his distance?

    this can be gotten by summing up all the individual distances covered by the person

    total distance= 15+10

    total diastance= 25 km

    b) what is the person’s displacement?​

    the displacement is the distance measured away from a point

    this can be gotten by subtraction the final distance/point from the initial distance/point

    displacement= 25-10

    displacement= 15km
