Detailed Analysis of Movements
To determine Lokesh's final direction relative to his starting point, we must calculate his net displacement using a coordinate system (North/South on the y-axis, East/West on the x-axis).
Movement 1: Start at (0, 0). Drive 15 km North.
New position: (0, 15)
Movement 2: Turn left (West) and drive 10 km.
New position: (-10, 15)
Movement 3: Turn left (South) and drive 5 km.
New position: (-10, 10)
Movement 4: Turn left (East) and drive 10 km.
New position: (0, 10)
