The question is extremely long so I'm not gonna bother typin it all out now, so I'll just give you the general idea.
Guy wants to make a movie with a robber running along the top of a train at a speed of 4 meters per second and a lawman on a horse running beside the train, with the train and the horse going at the same speed. The film maker wants it so that a camera on the ground will shoot the train as it moves past. He wants the robber, from the cameras point of view, to be moving at a rate of 25 meters per second.
Now I have to figure out how fast the lawmans horse must be able to run.
