If H equals 50 km/s/Mpc, then a galaxy with a radial velocity of 50,000 km/s will have a distance of about 1 Mpc.

If H equals 50 km/s/Mpc, then the Hubble law states that the recession velocity of a galaxy is proportional to its distance. Therefore, we can use the formula:

v = H x d

where v is the radial velocity of the galaxy, d is its distance, and H is the Hubble constant.

In this case, we have v = 50,000 km/s and H = 50 km/s/Mpc. Solving for d, we get:

d = v/H = 50,000 km/s / 50 km/s/Mpc = 1000 Mpc

So, the distance of the galaxy is not 1 Mpc, but rather 1000 Mpc, which is much farther away. Therefore, the answer is B (False).
