It has been found that galaxies are moving away from the earth at a speed that is proportional to their distance from the earth. This discovery is known as Hubble's law. The speed of a galaxy at distance from the earth is given by v = Hr, where H is the Hubble constant, equal to 1.58 × 10⁻¹⁸ s⁻¹. What is the speed of a galaxy?

(a) 5 × 10²² m from earth and

(b) 2 × 10²⁵ m from earth?

(c) If each of these galaxies has traveled with constant speed, how long ago were they both located at the same place as the earth?
