Q:  What is the value of the Hubble Constant based on this dataset?

        Using this data, the slope is roughly

                     1500 km/s                   km/s
            H0  =  -------------------  =   83  ------
                      18 Mpc                     Mpc


                         km          1000 m        1 Mpc
          H0  =    83 * -------  *  -------- *  ---------------
                        Mpc * s       1 km      3.1 x 10^(22) m


                                    1
              =   2.7 x 10^(-18)  -----
                                    s



 Q:  What is the age of the universe, based on this dataset?

         In this case, the age would be


              age  approx   3.7 x 10^(17)   seconds

                   approx   1.1 x 10^(10)   years


         An age of 11 billion years is much closer to the age
         of the oldest stars.
