yeah, well v=H X d. this relationship shows that the farther away a galaxy is to our own, the faster it is moving away from us. The product unit would be km/s per million LY. So if a galaxy has H of 20km/s per million LY, then the galaxy moves away from us at a speed of 20 km/sec for every million light years of its distance. As an example, a galaxy 100 million LY away is moving away from us at a speed of 2000 km/s.
