To solve this problem you must apply the proccedure shown below:

 1. You have that:

 - It completes one orbit every 5 hours.
 - The radius of earth is about 6,400 km.
 - The satellite is positioned 4,700 km above the earth. 

 2. Then, you must use the following formula:

 S=rθ

 r=6,400 km+4,700 km
 r=11,100 km

 3. When you substitute the values, you obtain:

 S=(11,100 km x 2π)/5
 S=13,949 km

 The answer is:13,949 km
