Imagine that you have obtained spectra for several galaxies and have measured the redshift of each galaxy to determine its speed away from us. Here are your results: Galaxy 1: Speed away from us is 15000 km/s. Galaxy 2: Speed away from us is 20000 km/s. Galaxy 3: Speed away from us is 25000 km/s. Estimate the distance to each galaxy from Hubble’s law. Assume that H0=22km/(sMly).
