As I can't really see the axes, all I can say is that the displacement vs. time graph looks reasonable. For the velocity vs. time graph note that since the direction of travel is in the negative direction, the velocity is negative. (This is for the "walking back" part after stopping for 15 min.) I am assuming the other velocities were in the positive direction. The problem statement doesn't actually say.
