Answer:
24 kilometers
Step-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!
Answer: 12 km
Step-by-step explanation:
The width of the coffee cup is 8 cm. This is the diameter of the coffee cup. You need to calculate the radius of the coffee cup with this formula:
[tex]r=\frac{d}{2}[/tex]
Where "d" is the diameter.
Sybstitutiing, you get:
[tex]r=\frac{8cm}{2}\\\\r=4cm[/tex]
Therefore, now you know that 4 cm represents the radius of Milky Way (approximately 50,000 light years), then the rest of the universe in centimeters is represented with:
[tex]x=\frac{(15,000,000,000\ light\ years)(4cm)}{(50,000\ light\ years)}=1,200,000cm[/tex]
From cm to km:
[tex]x=(1,200,000cm)(\frac{1km}{100,000cm})=12km[/tex]
