If a galaxy is found to have a recessional speed of 138,200 km/s, about how far away is it (in Mly)? (Assume the Hubble parameter is 20.8 km/s/Mly.) Mly The current estimate of the precision of the Hubble parameter is approximately ±5%. Determine the range within which the true distance to the galaxy lies. (Give your answers in Mly.) minimum distance Mly maximum distance Mly
