Question

The function f describes the distance of an airplane for its destination in miles t minutes after the plane takes off of f (93)=711 and f(97)=663 which of the following represents the average rate of change of f during the interval 93<_t<_97?

Answer 1

The function f (t) describes the distance of an airplane from its destination, in miles, t minutes after the plane takes off. If f (93) 5 711 and f (97) which equals 5

Answer 2

Answer: -27

Explanation:

To calculate the rate of change, you divide the total change by the amount of change. So...

97-93=4

711-663=108

108/4=27

Keep in mind that the distance is decreasing, so the rate of change is -27.
