Three people run a 100-meter race, starting from the starting point at the same time. When A finishes the race, B is still 25 meters away from the finish line. C is 60 meters away from the starting point. If the speed of the three-person race remains the same, when B reaches the finish line, how many meters will C be away from the finish line?
三人进行100米赛跑，同时从起点起跑，甲跑完全程时，乙离终点还有25米．丙离起跑点60米．如果三人赛跑的速度不变，那么当乙到达终点时，丙离终点还有多少米？
