On a 490-meter-long circular runway, two people, A and B, start from A and B, which are 50 meters apart, facing each other. 1/1, B's speed increases by 1/4. When B returns to point B, A just returns to point A, and at this time they are both moving forward at the current speed and direction. May I ask: When A catches up with B again, how many meters has A (counted from the start) walked in total?
在一个490米长的圆形跑道上，甲、乙两人从相距50米的A、B两地，相背出发，相遇后，乙返回，甲方向不变，继续前进，甲的速度提高五分之一，乙的速度提高四分之一．当乙回到B地时，甲刚好回到A地，此时他们都按现有速度与方向前进．请问：当甲再次追上乙时，甲(从开始出发算起)一共走了多少米？
