Bus 18 departs every 10 minutes.

Then when the car and the pedestrian are in the same direction, the pedestrian walked for 6 minutes from the time he met the first car to the time he met the second car, and the second bus took 6-x minutes from the point where the pedestrian and the first car met to catch up with the pedestrian.

When the vehicle and the pedestrian go in opposite directions, the pedestrian walks 3 minutes from meeting the first car to the second vehicle, and the second bus takes x-3 minutes from the meeting point with the pedestrian to the first bus meeting point.

Get: (6-x) (x-3)=6 3

Solution: x=4

A: Bus 18 departs every 4 minutes.

22:30-5:40 = 16:50, A: The service time of this bus is 16:50 a day;

So the answer is: 16:50
