Hubble's Law is:
Velocity = H × distance
H is the Hubble constant. So if we want to find the distance to a galaxy, we need to measure the velocity at which it is moving away from Earth
"Hubble's law, which says simply that a galaxy's velocity (or as is sometimes plotted, its redshift) is directly proportional to its distance, also tells us something important about the state of the universe." If the universe is static and unchanging, there should be no correlation between distance and velocity.
"Velocity is the speed at which something moves in a particular direction." For example the speed of a car travelling north on a highway, or the speed a rocket travels after launching. The scalar means the absolute value magnitude of the velocity vector is always the speed of the motion.
