Dr. M put the two robots "Lightning" and "Thunderbolt" invented by himself at points A and B at the two ends of a diameter of a circular runway with a circumference of 128 cm. The two robots start at the same time and go clockwise. Let's go, after a period of time "Lightning" catches up with "Thunderbolt" at point C, if "Lightning" moves 2 centimeters more per second, and "Thunderbolt" moves 2 centimeters less per second, then "Lightning" catches up with "Thunderbolt" The time will be reduced by 3 seconds, and the catch-up point is 24 cm away from point C. Let me ask: If two robots "Lightning" and "Thunderbolt" start from A and B at the same speed and walk towards each other at the same time, how long will it take? How many seconds to meet?
M博士将自己发明的两个机器人"闪电"和"霹雳"分别放在周长为128厘米的圆形跑道一条直径两端的A、B两点，这两个机器人同时出发都按顺时针同向而行，一段时间后"闪电"在C点追上"霹雳"，如果"闪电"每秒多走2厘米，而"霹雳"每秒少走2厘米，则"闪电"追上"霹雳"的时间会少用3秒钟，且追上的地点与C点相距24厘米，试问：如果"闪电"、"霹雳"两个机器人以原速度分别从A、B两地同时出发相向而行，需要多少秒钟相遇？
