Recall the raisin cake model of the universe and its analogy to our expanding universe. Suppose you measure the recession velocity (the speed at which any object is moving away from us) of Galaxy A to be 2000 km/s and the recession velocity of Galaxy B to be 6000 km/s. What can you conclude about the relative distances of these two galaxies?
A) Galaxy A is 3 times as far from us as Galaxy B.
B) Galaxy B is 3 times as far from us as Galaxy A.
C) Galaxy A is 6 times as far from us as Galaxy B.
D) Galaxy B is 6 times as far from us as Galaxy A.
E) The relative distances cannot be determined from the information in this problem.
B) Galaxy B is 3 times as far from us as Galaxy A.
