No, objects A and B do not have equal velocity. On a position-time graph, velocity is represented by the slope of the graph. Their slopes are different, so their velocities are never equal.
Fig. 4.27 shows a position-time graph of two objects A and B that are moving along the parallel tracks in the same direction. Do objects A and B ever have equal velocity? Justify your answer.

No, objects A and B never have equal velocity. In a position-time graph, the slope of the graph represents velocity. The graphs of A and B have different slopes throughout their motion. Although their position-time graphs intersect, this only means that they are at the same position at that instant. It does not mean that their velocities are equal. Therefore, their velocities are never equal.
