Answer:
DISPLACEMENT = 30KM
Explanation:
THE WORKER MOVES FORWARD FOR 40KM
AND AGAIN BACKWARDS FOR 10KM
THEREFORE
DISPLACEMENT IS THE SHORTEST PATH FROM INITIAL POSITION TO FINAL POSITION
SO CONSIDER A LINE ABC
AC = 40KM
THEREFORE HE MOVES BACKWARD 10 KM
SO
BC = 10
SO AB = AC - BC
AB = 30KM
DISPLACEMENT = 30KM
