The height, h, of a falling object t seconds after it is dropped from a platform 300 feet above the ground is modeled by the function h(t)=300-16t2. which expression could be used to determine the average rate at which the object falls during the first 3 seconds of its fall.

-96 feet/sec.

Step-by-step explanation:

The height h of a falling object after t second when it is dropped from a platform 300 feet above the ground is modeled by the function h (t) = 300 - 16t²

Then speed or average rate by which the object falls from height h will be

Speed = -

         = -16 (2t)

Speed = -32t

After 3 second speed of object will be

Speed = -32(3)

          = -96 feet/second

Therefore, the average rate will be -96 feet/sec. during the first 3 seconds of its fall.

based on context clues you gave i'm assuming the answer would be c.
