A company organized a group outing. Eight people rushed to the railway station by two cars. One of the cars broke down 15 km away from the railway station. At this time, there is still 42 minutes to stop the train checking in. At this time, only one car can be used, or they can walk. The average speed of the car is 60 km / h, and the walking speed is 5 km / h, Can all eight of them catch the train? (1) Can all the eight people catch up with the train if they can get back and forth by this car alone (2) Please come up with two plans to make these eight people catch the train (regardless of other factors)

When x is used, we meet the second group of people. According to the meaning of the question: 5x + 60x = 15 - (15 * 5 / 60), we get x = 11 / 12. When the car breaks down, it takes 15 / 60 + 2 * 11 / 52 = 35 / 52 for the second group of people to arrive at the railway station, 35 / 52 < 42
