What is the total displacement of a child who walks 4m south 2m north 5m south and 5 m north?

4 meters south - 2 meters north = 2 meter2 south

2 meters south + 5 meters south = 7 meters south

7 meters south - 5 meters north = 2 meters south

Total displacement = 2 meters South

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.

what is the actual question though?
