Question

I am very confused as to how to go about this?

Answer 1

The diameter of the sun is 1391400 km but in our model this is equal to 20 cm. To fint the distance from the sun to the star we need to use the rule of three:

`\begin{gathered} 1391400\rightarrow.0002 \\ 4.1315*10^(13)\rightarrow x \end{gathered}`

Then the distance in our model is:

`x=(4.1315*10^(13)\cdot0.0002)/(1391400)=5938.62`

From this, we can conclude that in our model the distance from the sun to the star is roughly the same distance from Washington to London, which is 5894 km.

Therefore the answer is 4.
