How to start with the application problems of MBA mathematics in previous years?
Hello, classmate. In fact, one thing that needs to be grasped about the application of this kind of ferrule is that one lap for each set means one more lap. Suppose the speed of A is V, then there is: the speed of B is 50m/min, then there is 25v=400+50×25, so we can get v=66. Therefore, the answer is C. This question should be the third question of the National Mathematics Entrance Examination for Management Postgraduates from June 2065438 to June 2003 10. I suggest you go and read the book "Analysis of Mathematical Zhenti over the Years" written by Time Peng.
