Question

desi hikes from the valley floor 385 feet below sea level to the top of the cliff 579 feet above sea level. use an integer to describe the distance that she hikes.

Explanation:

Step1: Define the starting and ending points

The starting - point is 385 feet below sea - level, which can be represented as - 385. The ending - point is 579 feet above sea - level, which is + 579.

Step2: Calculate the distance

The distance is the difference between the ending and starting points. We use the formula \(d=\vert579-(-385)\vert\). Since subtracting a negative is the same as adding a positive, \(579-(-385)=579 + 385\).
\[579+385 = 964\]

Answer:

964
