Answer:
2.5 m/s
0 m/s
Explanation:
Average speed is distance over time.
Average velocity is displacement over time.
The bicycle travels 150 meters from A to B, then 150 meters from B to A. So the distance is 300 meters and the displacement is 0 m.
s = 300 m / 120 s = 2.5 m/s
v = 0 m / 120 s = 0 m/s
