【Question 18】
There are two cars leaving the station one after another heading to the dock. The speed of the first car is 90 kilometers per hour. At 8:32, the distance of the first car from the station is 1.2 times the distance of the second car from the station; by 9:20, the distance of the first car from the station is twice the distance of the second car from the station. If the first car left the station at 8:08, how many kilometers per hour does the second car travel?
