To determine the distance and displacement of the journey described, let's break it down:
1. **Distance**: This is the total path length traveled regardless of direction.
- First part of the journey: 45 km east
- Second part of the journey: 90 m west (which is 0.09 km)
Total distance = 45 km + 0.09 km = 45.09 km
2. **Displacement**: This is the straight-line distance from the starting point to the ending point, considering the
