O A galaxy observed to be moving away from us at a speed of 7000 km/s is at a distance of about 100 Mpc from us. O A galaxy observed to be moving away from us at a speed of 700 km/s is at a distance of about 10 Mpc from us. A galaxy observed to be moving away from us at a speed of 70000 km/s is at a distance of about 1 Gpc from us.
