Question

rowan started at sea level and descended into a cave. her final location, in relationship to her starting point, can be represented by -90 feet. how many feet did she descend?
__ ft

Explanation:

Step1: Understand the problem

Rowan started at sea level (which is 0 feet). Her final location is -90 feet relative to the starting point. Descending means moving down, and the distance descended is the absolute value of the final position (since distance can't be negative).

Step2: Calculate the distance descended

The formula for the distance descended is the absolute value of the final position. So we calculate $| - 90|$. The absolute value of -90 is 90, because the absolute value of a number is its distance from 0 on the number line, and -90 is 90 units away from 0.

Answer:

90
