Answer:Hubble's initial value for the expansion rate, now called the Hubble Constant, was approximately 500 km/s/Mpc or about 160 km/sec per million-light-years.The units of the Hubble Constant are "kilometers per second per megaparsec." In other words, for each megaparsec of distance, the velocity of a distant object appears to increase by some value. (A megaparsec is 3.26 million light-years.)
