If galaxy A is four times more distant than galaxy B then....?
... according to the hubble law, how do the recessional velocities compare? Anybody know the answer, this question is killing me.

It shouldn't: v = H0 * d so four times more distant implies four times the recessional velocity.

The distance traveled of a object in a specific time. The relationship between the 2 galaxy in a frame of time. Light travels three hundred and sixty thousand miles per second. I Challenge this because we watch things happening is space now not ten thousand years ago. Light is instantaneous there is no time frame in the distance and time light travels, so the question is hypothetical. To my view.

permit the gap of galaxy B be "d". Distance of galaxy A = 4d velocity of recession for B (vB) = H (Hubble consistent) * d velocity of recession for A (vA) = H * 4d vA / vB = H * 4d / H * d = 4 for this reason, the respond is (b). HTH EDIT: Tina, I too, do agree that spoon feeding isn't the trick... yet come on. The asker wasted his/her 5 factors for it.
