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?
Accepted Solution
A:
Answer:24 kilometersStep-by-step explanation:It's a simple calculation using cross multiplication:We have the following ratios:[tex]\frac{8}{x} = \frac{50,000}{15,000,000,000} \\\\x * 50,000 = 8 * 15,000,000,000\\\\x = 2,400,000[/tex]That's 2.4 million of cm... or 24 000 meters... or 24 kilometers.That's equivalent to 300,000 cups placed side by side. That's a long way!
