To solve this problem, we need to set up a proportion based on the information provided. The path from the whales to the sharks (54 feet) is parallel to the path from the penguins to the fish tanks (x feet).
Since the paths are parallel, we can set up the proportion as follows:
\[ \frac{54}{x} = \frac{30}{54} \]
This means that the length from the whales to the sharks (54 feet) is to the distance from the penguins to the fish tanks (x feet) as the length of the segment from another reference point (here, 30 feet, presumably corresponding to another identified distance).
Now we can cross multiply to solve for x:
Cross Multiply: \[ 54 \cdot 30 = 54 \cdot x \]
Calculating the left side: \[ 1620 = 54x \]
Now, to solve for x, we divide both sides by 54:
\[ x = \frac{1620}{54} \]
Calculating this gives:
\[ x = 30 \]
Thus, the distance between the penguins and the fish tanks is:
\[ \boxed{30} \text{ feet} \]
Summary of answers:
- Set up the proportion: \(\frac{54}{x} = \frac{30}{54}\)
- Cross Multiply: \(30x = 1620\)
- Solve for \(x\): \(x = 30\) feet
