In an action movie, a spy is lying still on top of a train. the train is moving at a speed of 95 km/h. three bad guys are after the spy. one is in a helicopter flying above the train and moving at the same speed in the same direction as the train. the second is a spotter sitting above a tunnel opening that the train is headed for. the third is in a car that is driving alongside the train, in the opposite direction, at a speed of 105 km/h. which statement is supported by this scenario? the person in the car and the spotter above the tunnel will both observe the speed of the person on the train as 95 km/h. the person in the helicopter and the spotter above the tunnel will both observe the speed of the person on the train as 95 km/h. the spotter above the tunnel will observe the speed of the spy as 95 km/h, and the person in the car will observe the speed of the spy as 200 km/h. the person in the helicopter will observe the speed of the spy as 95 km/h, and the person in the car will observe the speed of the spy as 105 km/h.
