Question

The average speed of a certain particle in meters per second is given by the equation s(t)=(2t^2+8t+5)/(t+3)

Find the average rate of change as time changes from 0 seconds to 3 seconds.
Explain the meaning of this rate of change.

Answer 1

average rate of change = (s(3) - s(0)) / (3-0)

= .... m/s
