Starting position: Facing North
Turn right → Now facing East
Walk 20 meters → Position: 20 m East
Currently facing East
Turn left → Now facing North
Walk 30 meters → Position: 20 m East, 30 m North
Currently facing North
Move 20 meters to the right (East direction) → Position: 40 m East, 30 m North
Currently facing North
Turn right → Now facing East
Turn right again → Now facing South
Walk 55 meters → Position: 40 m East, 30 - 55 = -25 m (i.e., 25 m South)
Currently facing South
Turn right → Now facing West
Move 45 meters → Position: 40 - 45 = -5 m (i.e., 5 m West), 25 m South
Final position relative to starting point:
- Horizontal displacement: 5 meters West
- Vertical displacement: 25 meters South
Since she is both West and South of her starting point, she is in the South-West direction.
Therefore, the answer is Option 4: South-West.
