The hubble constant, $h_{0}$, is the ratio of the recessional velocity of a galaxy to its distance. the hubble constant is estimated to be 70 km/sec per million parsecs of distance. (one parsec is equal to 3.26 light years.) based on this ratio, how many billions of light years away would a galaxy be if it had a recessional velocity of 300,000 km/sec?
