Hubble breaks distance record by capturing universe’s early galaxy

SOLVED: Hubble's LawHubble's 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:v = HrWe are sending a spacecraft with constant velocity to a galaxy at a distance of r = 20 Mpc from us, and it is getting further away from us with a higher velocity as the universe expands! If the spacecraft reaches the galaxy after 7 billion years, determine
