10. An airplane’s altitude changed -378 feet over 7 minutes. What was the average change in altitude in feet per minute?

Underwater explorers found sea wreckage at a depth of 9,724.7 feet below sea level. They transported the wreckage to a storage area located at an altitude of 2,891.5 feet above sea level. What is the total change in the altitude of the sea wreckage?

When we work with altitude, below sea level is shown as:

• number zero

• positive numbers

• negative numbers

• only positive numbers
