A galaxy is measured to have a recessional speed from us of 1356 km/sec. Using the Hubble constant, how far away is this galaxy from us?
Added by Courtney B.
Step 1
As of now, the most commonly accepted value for the Hubble constant is around 70 km/s/Mpc (kilometers per second per megaparsec). We will use this value for our calculation. Show more…

(I) The redshift of a galaxy indicates a velocity of $1850 \mathrm{~km} / \mathrm{s} .$ How far away is it?
Suppose we could measure the distance to a galaxy using one of the distance techniques listed in Table 26.2 and it turns out to be 200 million light-years. The galaxy's redshift tells us its recessional velocity is $5000 \mathrm{km} / \mathrm{s} .$ What is the Hubble constant?
(I) If a galaxy is traveling away from us at $1.5 \%$ of the speed of light, roughly how far away is it?
