1. If a galaxy is located at a distance of 17.9 Mpc, and it is found to have recessional velocity of 1170 km/sec, what is Hubble's constant based only on this galaxy? Enter only the numerical value without the units.
2. Calculate the Hubble time (age of the universe) assuming the Hubble constant, H, to be 72.6 km/s/Mpc.
Do NOT enter your number in an exponential format but in a regular numerical format with correct number of "0"s and without the units.
