Show answer & explanation
Correct answer: B
Answer: 5 km towards North-East.
Step 1: Net north-south displacement = 10 km north − 6 km south = 4 km north.
Step 2: Net east-west displacement = 3 km east.
Step 3: Distance from start = √(4^2 + 3^2) = 5 km (a 3-4-5 right triangle).
Step 4: Direction = arctan(3/4) east of north, i.e., towards the north-east.
Therefore, the final position is 5 km towards the north-east from the starting point.
