Question

Consider a galaxy which is 100 million light-years away. Calculate it speed, assuming that the Hubble constant is 22 km/sec/million lt/years. Enter your answer in the blank (numbers only - no units!).

Answer 1

2200

Step-by-step explanation:

The Hubble law states that

v= H × d

where, v = speed, H = Humble constant, d = distance.

Thus

v=22 km/(sec/million ly)×100 million ly

=2200 km/sec.
