Question

The Kaibab Trail at the Grand Canyon begins at 7,000 feet above sea level. If you descend on the trail 4,500 feet to the Colorado River and then hike up 1,375 feet to a campsite, how many feet above sea level are you?

Answer 1

Answer:

3875 feet above sea level

Answer 2

Answer:

$3875$  $feet$

Step-by-step explanation:

We first start at 7,000 feet above sea level, we then descend 4,500 feet closer to the sea level, therefore:

$7,000 - 4,500$

$==> 2,500$

Then we go up 1,375 feet farther from the sea level, so:

$2,500 + 1,375$

$==> 3,875$
