The distance that a satellite orbits the Earth in one hour is of 1.1x10^7 m.
Due to this situation involves very long distance, it is much more convenient to use other units than meters. It is better to use a higher unit, as for example km. In this way the given distance of the trajectory of the satellite is better described, it's more simple and concatenated.
You know that 1 km = 1000m. This is the same that 1x10^3m = 1km. Thus, you can write the given distance in km units by proceeding as follow:
Hence, more appropriate units are km and the distance traveled by the satellite is 1.1 x 10^4 km
