Suzi starts her hike at 200 feet below sea level. When she reaches the end of the hike, she is still below sea level at −163 fee

Phantasy [73]

Answer:

Suzi's elevation in the hike is 37 feet.

Step-by-step explanation:

We are given the following in the question:

Position of Suzi in the starting of hike = 200 feet below sea level

= -200 feet

The negative sign shows below sea level.

Position of Suzi in the end of hike = -163 feet

Change in elevation from the beginning of Suzi's hike to the end of the hike

= Position of Suzi in the end of hike - Position of Suzi in the starting of hike

$=-163 - (-200)\\=-163 + 200\\=37\text{ feet}$

Thus, Suzi's elevation in the hike is 37 feet.
