To find the diver's elevation when he is halfway down to the treasure, we first need to determine what halfway down means.
The treasure is 97.2 feet below the surface. Halfway down would be:
\[ \frac{97.2 \text{ ft}}{2} = 48.6 \text{ ft} \]
This means that the diver would be 48.6 feet below the surface. Since elevation is often represented as a negative value when below sea level, we can express the diver's elevation as:
\[ -48.6 \text{ ft} \]
Looking at the options given:
- -145.8 π.
- -64.8 ft.
- -48.5 ft.
- -32.4 ft.
The closest answer is -48.5 ft, even though the exact value is -48.6 ft.
Therefore, the correct answer is -48.5 ft.
