This summer, Xiaoyu traveled to two cities, A and B. He found that the taxi charges in the two cities are different. The first city is the starting price.

(1) City A: 5+1+1.2 (a-3) =1.2a+2.4 (yuan);

B city: 6+1.4 (a-3) =1.4a+1.8 (yuan);

(2) (1.4a+1.8)-(1.2a+2.4) = 0.2a-0.6 (yuan),

Therefore, the difference between Xiaoyu and taxi A (A > 3) kilometers in A and B cities is (0.2a-0.6) yuan.
