Question

The milky way has a radius of approximately 50,000 light years. The visible universe has a size of approximately 15 billion light years. If the milky way is represented by an 8 centimeter wide coffee cup, how big would the rest of the universe be in kilometers

Answer 1

1875000000 Is the answer because you pretty much are being asked to divide so 15 billion divided by 8 is 1,875,000,000. Hope this helps:)
