According to the schedule, the first dispatch rider should leave point A, and 6 hours later, the second dispatch rider should leave with a speed that allows him to catch up to the first rider 180 km from point A. However, at the time of departure, the first dispatch rider received orders to travel at a speed "a" km/h faster than initially planned. The second dispatch rider was not allowed to increase his speed, so to precisely meet the assignment, he had to leave point A 3 hours earlier than originally planned. How much time will each dispatch rider be on the way?
