If you only need to find theHow do you calculate the average velocity of the car for the time interval t=0 to t=10.

However, the question has another part to it that I am stuck on it says:

How long after stating from rest is the car again at rest? Please Help and Thanks.

x(t)= bt^2 -ct^3, this finds the displacement as a function of time. You'll need another equation (related to this one) to find the velocity as a function of time.

Would I need the derivative of the displacement function?

Yes that would give you the velocity.

My next problem is how do I get t by itself?

Never mind I realized that I could use the quadratic formula.
