A school bus moves at 15 m/s relative to an outside observer. If a student walks toward the front of the bus at 3 m/s relative to the bus, how fast is the student moving relative to the observer? If the same student turns around and walks to the back of the bus at 3 m/s, what is the relative velocity of
the student to the observer?
