Final answer:
Using Hubble's Law with a Hubble's constant of 22 km/s/Mly, a galaxy located 10 million light-years away would be expected to move away from us at a speed of 220 km/s, which is option c) 220 km/s.
Step-by-step explanation:
When applying Hubble's Law, which is expressed as v = H0 × d, where 'v' is the recessional velocity of a galaxy, 'H0' is Hubble's constant, and 'd' is the distance to the galaxy, we can determine the expected velocity of a galaxy moving away from us based on its distance.
In this scenario, with Hubble's constant given as H0 = 22 km/s/Mly (kilometers per second per million light-years), a galaxy located 10 million light-years away would be moving away at a speed of:
v = H0 × d
v = 22 km/s/Mly × 10 Mly
v = 220 km/s
Therefore, the galaxy would be moving away from us at 220 km/s, which corresponds to option c) 220 km/s.
