If Heather runs at a speed of 10mph towards the train, she will reach point P (300 ft away to the left of her) at the same moment that the train does.  If she runs to point Q (500 ft to her right) at the other end of the bridge at the speed of 10mph, she will reach point Q also at the same moment that the train does.
