and B are training on the oval track, starting from the same place and running in the opposite direction at the same time, each person returns to the starting point after the first lap and immediately turns around and speeds up to run the second lap. When running the first lap, B's speed is (2/3) of A's speed, A's speed is increased by (1/3) when running the second lap, and B's speed is faster than the first lap when running the second lap The increase is (1/5). It is known that the point where A and B meet for the second time is 190 meters away from the point where they met for the first time. How long is this oval runway in meters?
甲、乙在椭圆形跑道上训练，同时从同一地点出发反向而跑，每人跑完第一圈回到出发点立即回头加速跑第二圈．跑第一圈时，乙的速度是甲的速度的(2/3)，甲跑第二圈时速度比第一圈提高了(1/3)，乙跑第二圈时速度比第一圈提高了(1/5)，已知甲、乙二人第二次相遇点距第一次相遇点190米，问这条椭圆形跑道长多少米？
