Answer:
39.4 feet below sea level
Explanation:
The difference between his starting and ending elevation is 83.9 feet, so we can write the following equation:
Start elevation - Final elevation = 83.9 feet
If we replace the starting elevation by 44.5 feet, we can calculate the final elevation as:
44.5 feet - Final elevation = 83.9 feet
Final elevation = 44.5 feet - 83.9 feet
Final elevation = -39.4 feet
So, the final elevation is -39.4 feet or 39.4 feet below sea level.
