The quantity...

Kind regards
A car is traveling on a straight road. For seconds, the cars velocity , in meters per second, is modeled by the piecewise-linear function defined by the graph below.
a.) Find . Using correct units, explain the meaning of .
b.) For each of and , find the value or explain why it does not exist. Indicate units of measure.
c.) Let be the cars acceleration at time , in meters per second per second. For , write a piecewise-defined function for .
d.) Find the average rate of change of over the interval . Does the mean value theorem guarentee a value of c, for , such that is equal to the average rate of change. Why or why not?
For a.) I came up with the answer 360 meters, I'm pretty sure that is correct.
For b.), I think the acceleration would be zero, correct me if I'm wrong.
I don't know what to do for c.) and d.) any help is appreciated, thanks.
