The galaxy is 7200 km/s moving away from us.

A Hubble is a large telescope in space.

The question can be solved using the formula below

⇒ Formula

  • v = Cd........................ Equation 1

⇒ Where:

  • v = Speed of the galaxy
  • C = Hubble constant
  • d = Galaxy's distance

⇒ Given:

  • C = 72 km/s/mpc
  • d = 100 mpc

⇒ Substitute these values into equation 1

  • v = 72(100)
  • v = 7200 km/s.

Hence, the galaxy is 7200 km/s moving away from us.
