For any object moving uniformly, velocity = distance/time. If so, in the Hubble relationship for the expansion of the universe, v = H0r, what is the significance of the constant 1/H0?
A)   It represents the average spacing between objects in the universe at the present time.
B)   It represents the time since the expansion began, or the age of the universe.
C)   It is merely a constant of proportionality, to allow for the different units in v and r.
D)   It is the inverse of the velocity that the object would have at a standard distance of 10 parsecs.
