The distance time graph shows a cart moving at a straight path.
a. Describe the speed of the cart between:

1.) A and B - The cart is moving with constant speed for 10 seconds and it is now at rest for 20 seconds.
2.) B and C - The cart at rest for 20 seconds will now start moving with acceleration for 10 seconds.
3.) C and D - The cart starts to move with acceleration for 10 seconds.

b. What is the total distance traveled?
c. What is the average speed of the cart?
