Answer :
60 meters, because he starts at point A and moves with a constant velocity of 0.5 m/s for 120s,
0.5x120=60
so the displacement is 60 meters, because the displacement is the distance between the starting point and the finishing point.
0.5x120=60
so the displacement is 60 meters, because the displacement is the distance between the starting point and the finishing point.
