Two trains travel toward each other on the same track, beginning 100 miles apart. one train travels at 40 miles per hour; the other travels at 60 miles an hour. a bird starts flight at the same location as the faster train, flying at a speed of 90 miles per hour. when it reaches the slower train, it turns around, flying the other direction at the same speed. when it reaches the fastest train again, it turns around -- and so on. when the trains collide, how many miles the bird has flown.
