ANSWER:
Solution 64PE
Step 1 of 7
In the given problem, relative velocities and distances are given for five different galaxies as shown in the figure below. The given velocities of the galaxies are relative to milky way galaxy whereas the the given distances are the distances of the other galaxies from milky way galaxy.
Here we need to calculate the average rate of expansion as a function of distance and also we need to find how long back does the galaxies were at the same position.
The relative velocity is the velocity of an object measured from a particular reference frame and it will vary as the reference frame changes.
