    From memory it varies between about 67km/s per megaparsec to 74km/s per megaparsec.

    Also it’s really weird to describe something in terms of km/s when you look at an area over millions of lightyears

      Those are weird units indeed :
      (1 km /s) / 1 mega parsec =
      (1000 m/s)/(106 x 3.0857×1016 m) =
      1/3.0857×1019 seconds =
      1/978 x109 years.

      So, when we multiply by the rates (which are either 67 or 74) we get :
      1/ 14.6 giga years or
      1/ 13.2 giga years
      … basically ( 1/ “age of the universe”).

      Meaning physical observation disagree about the age of the universe …or the theory is faulty.
