Do you know how to get the gradient of a straight line? If not, you'll want to revise that topic first. Give us a shout if you're not sure.

My answer is A: 2km/sec. N of E B: 1.2km/sec. East C: 0.14m/sec. N of W D: 1.33m/sec. East How is it? Have I done it right? O.o

fyi, the graph represents motion in one dimension ... unless you have additional information, all you can say is that the velocity is moving in the negative direction, positive direction, or at rest. the object is at rest during time intervals B and D the object is moving in the positive direction during time intervals A and E the object is moving in the negative direction during time interval C
