the radius is 7000km and the satellite revolves around the earth. So, first we have to find the circumference of the path which is equal to the diameter.
Therefore, C=2πr
C=2*22/7*7000
C=2*22*1000
c=44000km.
Time is already given to us which is 2 hrs.
Therefore we can calculate by the formula Speed=Distance/Time
S=44000/2
S=22000km/hr
