Hey guys! I have a problem that I don't understand. I don't know how to interpret this graph and hence find the velocity of the car - it is mainly I don't know how to interpret the direction and what the Velocity (m/s South means). Does it mean that the positive y-axis of the graph is now south and the negative axis of the graph is now North???

Also how do I find the instantaneous velocity at 6s for this question:

And this question makes no sense:

I did this:

But apparently it is wrong and the answer says this:
