Then how come we can tell how fast an object is moving away by it "red
shift".

Sorry to interject here but according to Einstien's second postulate of
relativity the speed of light is constant no matter what speed the observer
travels at. So if we were to assume that light travelled at 1157.407 miles
per sec and the observer also travelled at this speed he could still see
quite well as the light he observes continues to travel at 1157.407 miles
per sec.....honest guv!!!
