Final answer:
The displacement of the person is 0 meters since they return to their starting point after walking 150.25 meters west and then back in the opposite direction.
Step-by-step explanation:
The question revolves around the concept of displacement, which is a vector quantity representing the shortest path between the initial and final positions of a point P. For the scenario described, since the person walks 150.25 meters west and then walks 150.25 meters back in the opposite direction, they end up exactly where they started. Therefore, the displacement is 0 meters.
The correct answer to the question is a. 0 meters. Displacement is concerned with the difference between the starting and ending points of a journey, and in this case, because the person returns to the starting point, the displacement is zero. It is important to note that displacement differs from distance, which would have been 300.5 meters for the total journey walked (150.25 m + 150.25 m).
