Answer:
B.
Explanation:
Dong did not go home since he is 500 meters west and 300 meters north away from his home, Dong also did not travel a less distance than Anna since Anna only walked 200 meters. If you add up the distance he traveled, which is 100+300+200+400, it will give you 1,000 meters. Which means the only correct answer is letter B, Dong traveled a total distance of 1,000 meters.
