Zhang Ming rides a bicycle at a speed of 14 kilometers per hour, and Wang Hua rides a motorcycle at a speed of 35 kilometers per hour. They start from two points A and B respectively, and continue to drive back and forth between A and B. The place where people meet for the fourth time (two people arrive at the same place at the same time is called meeting) is exactly 120 kilometers away from the place where they meet for the fifth time. Then, what is the distance in kilometers between places A and B?
