A commercial jet liner hits an air pocket and drops 212 feet. After climbing 151 feet, it drops another 179 feet. What is its overall vertical change?
The overall vertical change can be determined by adding the individual vertical changes.
First, the jet liner drops 212 feet.
Then, it climbs 151 feet.
Finally, it drops another 179 feet.
Therefore, the overall vertical change is -212 + 151 - 179 = -240 feet.
Note that the negative sign indicates that the jet liner went downwards.
To find the overall vertical change, we need to add up all the changes in altitude.
First, the jet liner drops 212 feet. We'll represent this as -212.
Next, it climbs 151 feet. We'll represent this as +151.
Finally, it drops another 179 feet. We'll represent this as -179.
To find the overall vertical change, we add these values together:
-212 + 151 + (-179)
Simplifying:
-212 + 151 - 179
-379 - 179
= -558
The overall vertical change of the jet liner is -558 feet. This means it has descended 558 feet.
To find the overall vertical change, we need to calculate the sum of the two individual changes: the drop of 212 feet and the drop of 179 feet, after climbing 151 feet.
First, add the two drops:
212 feet + 179 feet = 391 feet
Then, subtract the climb:
391 feet - 151 feet = 240 feet
Therefore, the overall vertical change of the commercial jet liner is 240 feet.
