Look, the bridge is 525 meters long but if a train wants to cross it then it will be 625 meters long because for crossing the bridge the last point of the traint should cover 100 meter distance more.For speen if we convert the speed in m/s then it will be 20 m/s so the time taken by the train to cross a bridge= distance / speed= 625 / 20= 31.25 seconds
