To find the rate of change in the plane's altitude, we can calculate the quotient of the altitude change and the time taken.
The plane descends 4,000 feet over a time period of 3.5 minutes.
To find the rate of descent in feet per minute, we use the formula:
\[ \text{Rate} = \frac{\text{Change in altitude}}{\text{Time}} = \frac{-4000 \text{ feet}}{3.5 \text{ minutes}} \]
Now perform the division:
\[ \text{Rate} = \frac{-4000}{3.5} \approx -1142.8571428571 \]
When rounding to the nearest hundredth, we get:
\[ \text{Rate} \approx -1142.86 \text{ feet/minute} \]
Since the plane is descending, the negative sign indicates that the altitude is decreasing.
Thus, the quotient that best represents the rate of change in the plane’s altitude is approximately
-1142.86 feet/minute.
