To find the constant rate of change of velocity for the car based on the given points on the graph (0, 60), (1, 40), (2, 20), and (3, 0), we need to calculate the slope of the line connecting these points. The constant rate of change (slope) between two points can be found using the formula:

 

Let's calculate the slope between consecutive points:
Between (0, 60) and (1, 40):
