To find out how far the submarine traveled, we need to calculate the difference between its initial and final depths.
- Initial depth: 106.3 feet below sea level
- Final depth: 481.2 feet below sea level
To find the distance traveled, we can subtract the initial depth from the final depth:
\[ \text{Distance traveled} = \text{Final depth} - \text{Initial depth} \]
\[ \text{Distance traveled} = 481.2 \text{ feet} - 106.3 \text{ feet} \]
\[ \text{Distance traveled} = 374.9 \text{ feet} \]
Therefore, the submarine traveled 374.9 feet.
