Question

Todd begins to walk down a mountain with an elevation of 80 meters above sea level. He hikes all the way down to the valley (below sea level) with an elevation of -40 meters. What is his change in elevation?

Answer 1

The change in elevation is -120 meters.

Step-by-step explanation:

To find the change in elevation, we subtract the initial elevation from the final elevation. Todd begins at an elevation of 80 meters above sea level (-40 meters below sea level) and descends to -40 meters. The change in elevation is:

Change in elevation = Final elevation - Initial elevation

Change in elevation = (-40 meters) - (80 meters)

Change in elevation = -120 meters

Therefore, Todd's change in elevation is -120 meters.
