    Which of these statements are true?

    A The value of the Hubble constant is 70.4 km s−1 kpc−1, with an uncertainty of about 1.5 km s−1 Mpc−1 .

    B The apparent speed of recession of a galaxy is given by the product of the Hubble constant and the distance to the galaxy.

    C The further away a galaxy is, the lower its apparent speed of motion away from us.

    D A galaxy with a redshift of 5.37 is situated at a look-back time of 4.1 billion years.

    E Space is expanding uniformly so that the distance between galaxies remains constant.

    Is B the correct statement?
