Test yourself: pick an answer
Reveal answer & explanation
Correct answer: B) 10 km
Explanation
Turning right from North means facing East. His displacement is 6 km North and 8 km East, so distance = √(6² + 8²) = √100 = 10 km. Adding the distances (14 km) gives the path length, not the distance from the start.
