To calculate both distance and displacement in this scenario:
1. **Distance** is the total length of the path traveled, regardless of direction.
- You moved 25 meters north and then 30 meters south.
- Thus, the total distance = 25 m + 30 m = **55 meters**.
2. **Displacement** is the change in position from the starting point to the final position, taking direction into account.
- You start 25 m north, then move 30 m south.
- The
