Answer:

25.9 feet per second.

Step-by-step explanation:

For the first 14 seconds, the change in elevation was –65×14= –910 feet.

For the remaining 6.5 minutes, the change in elevation was –1,470×6.5 = –9,555 feet.

The overall change in elevation was –910+ –9,555= –10,465 feet.

The total number of seconds was

6.5×60=14+390=404 seconds. The Average change in elevation was −10,465÷404=25.9 feet per second.

IgorLugansk [536]
A graph shows the limit to be 1/2.
https://www.desmos.com/calculator/qrf6ay47tw

Since the value of the function is the indeterminate form 0/0, L'Hôpital's rule applies. The ratio of derivatives of numerator and denominator is
.. x/\sqrt{x^{2}+3 }
Evaluated at x=1, this is
.. 1/\sqrt{1^{2}+3 } = 1/2
