Hi there!
The period of an orbit can be found by: 

T = Period (? s)
r = radius of orbit (6400000 m) 
v = speed of the satellite (8000 m/s) 
This is the same as the distance = vt equation. The total distance traveled by the satellite is the circumference of its circular orbit. 
Let's plug in what we know and solve.
