A train travels North at a speed of 50 m/s. A passenger walks toward the rear of the train at a speed of 2m/s. A person standing on a platform at the train station observes the motion of the pssenger as the train passes. According to the information from the previous paragraph and the diagram, what is the relative speed of the passenger with respect to the train station platform?
