A beach ball rolls off a cliff and onto the beach. The height, in feet, of the beach ball can be modeled by the function h(t)=64–16t2, where t represents time, in seconds.

What is the average rate of change in the height, in feet per second, during the first 1.25 seconds that the beach ball is in the air?

I got the answer 39 is that correct?

h(1.25) = 39
h(0) = 64
avg rate of change is totaldisplacement/totaltime = (39-64)ft/1.25s = -20ft/s

you only found the displacement, not the rate of change.
Oh okay thank you but I got the anwser 20 instead of negative -20
Nvm I did the calculations wrong you were right. Thanks again for your help
