    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?

    distance = rate x 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 |dw:1351868677072:dw|

    how fast do you have to be going to not move?

    :) 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?

    Uh no, that graph is the only information ive been given

    Other than the problems I typed

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