Answer:
The question is incomplete,
the displacement time graph is missing. Check attachment for the graph.
Explanation:
Average velocity can be find by using
Average velocity = change in displacement / time taken
A.V = ∆y / ∆t
So, at time t1 = 4s, the position of the body is at 2m
y1 = 2m
Also, at time t2 = 10s, the position of the body is at 5m
y2 = 5m.
So,
A.V = ∆y / ∆t
A.V = (y2 - y1) / (t2 - t1)
A.V = (5 - 2) / (10 - 4)
A.V = 3 / 6
A.V = 0.5m/s
So, the average velocity is 0.5m/s
