      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.
