Assuming a constant rate of expansion, what relationship does a higher $H_0$ value suggest about the age of the universe?

Answer

It implies a younger age.

A faster expansion rate (higher $H_0$) means the universe took less time to reach its current size, suggesting a younger age when assuming constant expansion.
