Final answer:
The walked distance is 1.5 km, the displacement is zero, the average speed is 1 km/h, and the average velocity is zero.
Step-by-step explanation:
To find the walked distance, we need to sum up the distances between each location. From the given information, you start at the CAFE and walk to the ART GALLERY, which let's say is 0.5 km. Then, you walk from the ART GALLERY to the BAKERY, which let's say is 1 km. So, the total distance traveled would be 0.5 km + 1 km = 1.5 km.
To find the displacement, we need to determine the net change in position. In this case, since you return to the CAFE, the displacement would be zero because there is no change in position.
The average speed is calculated by dividing the total distance traveled by the total time taken. In this case, the total distance traveled is 1.5 km and the total time taken is 1.5 hours. So, the average speed would be 1.5 km / 1.5 hours = 1 km/h.
Velocity, on the other hand, takes into account both the magnitude and direction of the motion. Since the displacement is zero, the average velocity would also be zero.
