Question

Jamal is rock climbing. He starts off 44.5 feet above sea level and descends down the mountain. The difference between his starting and ending elevation is 83.9 feet. What is Jamal's final elevation?

Answer 1

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.
