A commercial jet liner hits an air pocket and drops 261 feet. After climbing 127 ​feet, it drops another 134 feet. What is its overall vertical​ change?

Answer 1

To find the overall vertical change, we need to calculate the sum of the positive and negative changes.

Positive change: climbing 127 feet
Negative change 1: dropping 261 feet
Negative change 2: dropping 134 feet

Overall vertical change = 127 + (-261) + (-134)
= 127 - 261 - 134
= -268 feet

Therefore, the overall vertical change is -268 feet.
