Show answer & explanation
Correct answer: B
Raj walks 5 km North. Then he turns right (East) and walks 10 km. Next, he turns left (North) and walks another 5 km. Finally, he turns left (West) and walks 10 km.
Horizontal Displacement: 10 km East + 10 km West = 0 km.
Vertical Displacement: 5 km North + 5 km North = 10 km.
The straight-line distance back to home is the total vertical displacement, which is 10 km.
