Explanation:
For a circular orbit v= with G = 6.6742 ×
Given m = 6.42 x 10^23 kg and r=9.38 x 10^6 m
=> v = 2137.3 m/s
I hope this is the correct way to solve
Average speed is defined as ratio of total distance covered and total time
now we will have
now total distance moved is
total time is given as
now average speed is given as
so its average speed is 0.1 km per minute
