Question

How many galaxies like our own would it take if they were placed edge-to-edge to reach the nearest galaxy, which is about 2.5 million light-years away? (The diameter of the Milky Way Galaxy is about 8.0 x 104 light-years.) O a. About 31 galaxies. O b. About 340 galaxies. O c. About 16 galaxies. O d. About 48 galaxies.

Answer 1

The question wants the number of milky ways between us and the nearest galaxy

Let’s say x is the number of the galaxies

x * diameter = distance

x= distance/diameter

Substituting

x= (2.5 x 10^6) / (8 x 10^4) ≈ 31

So the answer should be A. Hope this helps
