The railway between station a and station B is 1800 km long. At 10:30 pm on September 30, a train runs from station a to station B at a speed of 90 km per hour At 12:00 that night, a train was going from station B to station a at the speed of 95 kilometers per hour. What month, day and hour did the two trains meet
According to the meaning and known, there are: (95 + 90) x = 1800-90 (12-10.5) 185x = 1665x = 12:00 on the night of October 30, which is 0:00 a.m. on October 1, 0:00 on October 1, 0:00 + 9 = 9:00 on October 1
