Ok this is the graph, how fast is the car going from A-B and how fast is the car going from B-C?

do you know a formula for speed?

Speed =Distance / time?

Are you supposed to answer in variable terms?

I know, thats the problem Im having... and maybe variables?

the distance covered from B to C is what? ignore the time part, how much does the distance change?

Well If I was to put up markers, about 2/3 as much as A-B... I really am uninformed in this topic...

the orientation of the chart might be confusing

:) so at least from B to C, the speed is zero

But in A-B your distance variable is going up right?

correct, you are changing your distance from A to B by constant rate, and if we were able to have some points of reference we would be able to determine the speed by finding the slope of the line from A to B

are the point values for A and B given in a different part of the problem set?

then the only thing we can really deduce is that the speed from A to B is greater than zero :)
