By what factor would the critical density of the universe today change if the Hubble constant today measured at 5 times greater than what we previously thought?

If the average density of the Universe is small compared with the critical density, the expansion of the Universe described by Hubble's law proceeds with speeds that are nearly constant over time. Calculate t since the big bang, assuming H = 22.0 km/s/Mly.
