If you are riding on a train that is going 60 MPH, and you are running from the back to front at 5 MPH. How fast does the person on the ground see you running.
If you are running 2 MPH on the earth, relative to you or anyone on earth, the earth is not moving. If you are at a point where you are observing the earth going 1,000 MPH, observing only you, you will be traveling at 1002 MPH.
