Two distant galaxies are observed to have redshifts z₁ = 0.05 and 22 = 0.15, and distances d₁ = 220.60 Mpc and d₂ = 661.75 Mpc, respectively. Assuming the motion of the galaxies is due to the Hubble flow, determine the value of the Hubble constant, Ho. Show how the value of Ho can be used to estimate the age of the Universe, describing any assumptions that you make. Use the value of Ho you have obtained to estimate the age of the Universe, expressing your answer in Gyr.
