When the speed of the car is greater than or equal to the speed of the bicycle, the distance begins to decrease, so when the speed of the car is equal to 6, the distance is the farthest, at this time t = 2S, the displacement of the car is 0.5at ^ 2 = 6m, and the distance of the bicycle is 12M, so the distance is 6m
