1. A bus starts a 100-kilometer journey at 12:20 PM. There is a computer on the bus that at 1:00 PM, 2:00 PM, 3:00 PM, 4:00 PM, 5:00 PM, and 6:00 PM, says: “If the average speed in the future is the same as the average speed in the past, then it will take one more hour to reach the destination.” Is this possible? If so, how far has the bus traveled by 6:00 PM?
