If a galaxy is located at a distance of 18 Mpc,and it is found to have recessional velocity of 1170 km/sec,what is Hubble's constant based only on this galaxy?

Question

Quizplus · Accepted Answer

Hubble's constant is given by the formula H = v/d, where v is the recessional velocity and d is the distance. In this case, v = 1170 km/sec and d = 18 Mpc, so H = 1170 km/sec / 18 Mpc = 65 km/sec/Mpc.
