ANSWER:
The velocity is 29884.89 m/s
The avergae velocity is 0 m/s
Explanation:
We know that the speed is given by the distance for a certain time (in this case a year).
We know that the distance traveled would be equal to the circumference of the circle formed, which can be calculated by means of the radius.
We have the following equivalences:
1 km = 1000 m
1 year = 365 days
1 day = 24 hours
1 hour = 60 minutes
1 minute = 60 seconds
Therefore, we calculate the velocity as follows:
Now, since the initial and final position are the same, we would have:
