If a galaxy is moving away from us at 1.0% of the speed of light, use Hubble's law to estimate how far away it is from us if the Hubble constant is 22 km/s per million light-years. (c = 3.00 × 108 m/s, 1 ly = 9.461 × 1015 m, 1 y = 3.156 × 107 s)

A) 140 ly
B) 14 ly
C) 140 thousand ly
D) 140 million ly
