At the beginning of the working day, the bus went on the route, and in the evening it returned to the motor depot. During a working day, the reading of the meter installed in the driver’s cab increased by 150 km. What are the module of movement and the distance traveled by the bus?

Let’s introduce a coordinate system associated with the movement of the bus. Then the bus starts its journey from the zero coordinate x0, which corresponds to the position of the carpool. Having completed a certain route, he returns back to the motor depot at the point x0. Since the meter readings have increased by 150 kilometers, it means that the distance covered by the bus is S = 150 kilometers. Since after completing the route, the bus returned to the same point from which it began its movement (x0), the movement of the bus is 0.
Answer: the distance traveled is 150 kilometers, the displacement is 0.
