Hubble's law is described mathematically as _____. Group of answer choices v = H0 / d where H0 is called Hubble's constant, v is velocity, and d is distance v2 = H0 d where H0 is called Hubble's constant, v is velocity, and d is distance v = H0 d where H0 is called Hubble's constant, v is velocity, and d is distance v = H0 - d where H0 is called Hubble's constant, v is velocity, and d is distance
