To find the mean change of altitude in feet per minute, you can use the formula:

\[
\text{Mean Change} = \frac{\text{Total Change in Altitude}}{\text{Total Time}}
\]

In this case, the total change in altitude is -378 feet and the total time is 7 minutes.

Now, plug the values into the formula:

\[
\text{Mean Change} = \frac{-378 \text{ feet}}{7 \text{ minutes}} = -54 \text{ feet per minute}
\]

So, the mean change of altitude is **−54 feet per minute**.
