Answer:

The age of the universe would be larger.

Explanation:

The Hubble relation states that an astronomical object's velocity is proportional to the distance between the observer and the object.

v = dH₀

where

d is the distance between the observer and the object.
H₀ is the Hubble constant

If the Hubble constant decreases, the velocity will decrease.

Time is determined by taking the quotient between the distance and the velocity.

T = d/v

Therefore, since the velocity decreased, the time increases. Thus, if H₀ was found to be smaller than thought, the age of the universe would be larger.
