In 1984, the six mathematics examination papers for high school and secondary school students from six suburban counties in Nantong, Jiangsu Province set out the following topics: From A to B, A from B to A. If A is 2 kilometers ahead, it meets B at the midpoint of AB after 2 hours. If it starts at the same time, it will take 2 (1/2) hours to reach B, and B goes 1 (3/5 ) Hours to A. What is the speed of seeking A and B? The answer given in this question and answering the scoring standard is that A goes 4 kilometers per hour, B goes 5 kilometers per hour, but some candidates answer the answer is A Hours walk 24 km,
