To find how far the submarine traveled, we need to calculate the difference in depth between the initial and final positions.
The initial depth of the submarine is: -106.3 feet (below sea level)
The final depth of the submarine is: -481.2 feet (below sea level)
We can calculate the distance traveled by finding the difference between the two depths:
\[ \text{Distance traveled} = \text{Final depth} - \text{Initial depth} \]
Substituting the values:
\[ \text{Distance traveled} = -481.2 - (-106.3) \] \[ = -481.2 + 106.3 \] \[ = -374.9 \text{ feet} \]
Since we are interested in the distance traveled (a positive value), we take the absolute value:
\[ \text{Distance traveled} = 374.9 \text{ feet} \]
Therefore, the submarine traveled 374.9 feet.
