Suppose two galaxies move away from each other at 6000 km/sec and
are 300 million (3x10³) light-years apart. If their speed has remained
constant, how long has it taken them to move that far apart? Express
your answer in years. (2points)

You find a small satellite galaxy orbiting 66 kpc from the center of a larger galaxy at a speed of 210 km/s. What is the total mass of the galaxy-satellite galaxy system? (Give your answer in terms of MSun.)
In the reading, you were told that there were roughly 10,000 galaxies in the image of the Hubble Ultra Deep Field alone. The image is roughly 10 square arcminutes and there are roughly 1.5*10^8 square arcminutes composing the entire sky. With that in mind and assuming that the Hubble Ultra Deep Field represents an average part of the sky, roughly how many galaxies may exist in the observable universe?
