Help me please I can't get the final step

Explanation:

Dimensional Analysis

It's given the relation between quantities A, B, and C as follows:

and the dimensions of each variable is:

Substituting the dimensions into the relation (the coefficient is not important in dimension analysis):

Operating:

Equating the exponents:

Adding both equations:

Solving:

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
