the distance traveled, in meters, of a coin dropped from a tall building is modeled by the equation d(t) = 4.9t^2 where d equals the distance traveled at time t seconds and t equals the time in seconds. what does the average rate of change of d(t) from t = 3 to t = 6 represent?

a. the coin travels an average distance of 44.1 meters from 3 seconds to 6 seconds.

b. the coin falls down with an average speed of 14.7 meters per second from 3 seconds to 6 seconds.

c. the coin falls down with an average speed of 44.1 meters per second from 3 seconds to 6 seconds.

d. the coin travels an average distance of 14.7 meters from 3 seconds to 6 seconds.
