A car is stopped at a traffic light. It then travels along a straight road so that its distance from the light is given by x(t)= bt^2 -ct^3, where b = 2.40m/s^2 and c = 0.120 m/s^3. How do you calculate the average velocity of the car for the time interval t=0 to t=10.(adsbygoogle = window.adsbygoogle || []).push({});

I think that maybe I need to take the derivative of the equation but then what please help!
