Answer :
Note : Be careful with speed and velocity, even the formula is same that [tex]v = \frac{x}{t} [/tex]
1. If we would like to find the velocity, we must calculate the distance from initial to final, [tex] x_{f} - x_{i} = (delta)x[/tex],
2. If we would like to find the speed, we must calculate the total distance that travelled ([tex] x_{total} [/tex].
So, in this question, because it return back to its initial point so (delta)x = 0, so average velocity is 0 m/s.

So, in this question, because it return back to its initial point so (delta)x = 0, so average velocity is 0 m/s.
If you mean average speed, it is 480/10 = 48 kn/h
If you mean average velocity, it is 0/10 = 0 km/h
If you mean average velocity, it is 0/10 = 0 km/h
