The statement, which correctly describes the motion of the buses is this: THE AVERAGE SPEED OF THE BUSES IS EQUAL.
Speed is defined as the distance traveled per unit time; it measures the rate of moving of an object. It is a scalar quantity, that is, it has only magnitude and no specific direction and it is measured in meter per second.
