29. A group of hikers on a mountain began at an elevation of 3040 feet above sea
level and stopped at an elevation of 2319 feet above sea level. What was their
change in elevation between these points? How can you tell from the change
in elevation whether the hikers were going up or down the mountain?

Respuesta :

Answer:

  • The change was 721 feet down.

Step-by-step explanation:

Starting point:

  • 3040 ft.

Ending point:

  • 2319 ft.

Given equation:

  • 3040 - 2319

Solve:

  • 3040 - 2319
  • = 721.

The change in elevation was 721 feet down.

Change in elevation: -721 feet
You do 3,040 - 2,319 = 721 which gives us the change of elevation.
We can tell from the change in elevation that the hikers are going down the mountain because they started at a higher position and then ended at a lower position.
