What law states that the galaxies are retreated from the Milky Way at a speed that’s proportional to their distance?
A
Hubble’s Law
B
Newton’s 1st Law
C
Einstein’s Theory of Relativity
D
Kepler’s 2nd Law
Explanation: 

Detailed explanation-1: -Hubble’s law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away from Earth.

Detailed explanation-2: -The motion of galaxies in the universe appears to be a smooth recession away from each other. Also, the velocity of a galaxy away from any observer is proportional to the distance from that observer.

Detailed explanation-3: -The data points generally fall close to a straight line, indicating that the rate at which a galaxy recedes is directly proportional to its distance from us. This rule is called Hubble’s law.
