Answer #1

Assuming that the train is moving at a constant speed,

Position of the rear end of the train after 100 seconds,

Also, the position of the patient as compared to the rear end of the train is 200 m (As he is seated at the middle of the train)

Position of the passenger according to the paramedic,
