The distance between the two missiles is 41620 kilometers, and they are traveling towards each other on the same route. One of them is flying at a speed of 38,000 kilometers per hour, and the other is flying at a speed of 22,000 kilometers per hour. May I ask: how many kilometers are they separated in 1 minute before the collision.
两枚导弹相距41620千米，处于同一路线上彼此相向而行．其中一枚以每小时38000千米的速度飞行，另一枚以每小时22000千米的速度飞行．请问：它们在碰撞前的1分钟时相距多少千米．
