To determine the correct proportion that represents the distance between the penguins and the fish tanks, we can set up the parallel paths based on the provided information.
We can represent the problem using similar triangles. If the distance from the whales to the sharks is represented as 30 units (for instance) and the distance from the penguins to the fish tanks is represented as \( x \), and knowing the other distance that parallels this path is 45 (from the whales to the sharks, for instance), we can set the proportion in this manner considering their similarities:
\[ \frac{30}{45} = \frac{x}{54} \]
Given the options in your question, none of them appears to match this format directly. However, if we rearrange the ratios correctly, we align more closely with one of the options.
Therefore, the likely valid proportion is:
\[ 30:45 = x:54 \]
This means that:
\[ \frac{30}{45} = \frac{x}{54} \]
Finally, since it's expressing a direct relationship, the basic form would yield the correct distance (54) corresponding directly to the initial distance ratio.
So choose the option corresponding to the setup involving the distance of penguins to fish tanks \( x \), and the ratios can be simplified accordingly if one matches.
Confirming through elimination:
- \( 30 : 54 = x : 45 \) would not work as \( 30 \neq x \)
- \( 54 = 45x \)
Ultimately, based on the sets, the correct identification should yield a direct proportion expressing how they align with parallel structures, which simplifies down to either \( 30:45 \) correlating to \( x:54 \) under comparative measure within the correct backdrop of geometry related to triangle similarity factors.
Look again for the exact wording of the proportion in problem statements or any formvalues if adjustments fit correctly!
