... Any answer consistent with value of z from question 3 is acceptable. For example, vrec = 1,800 km s-1 (for z = 0.006) 5. Hubble observed that all distant galaxies show a redshift, which shows galaxies are moving further apart. Since the most distant galaxies appear to be travelling the quickest, thi ...
