(2 1 figure 2? Jinan) The distance between two E's is 1km. Two cars A and B start from two E's at the same time and meet at 23v. The speed ratio of two cars A and B is 4: 5.

The sum of the speeds of the two cars is:

9 It ÷23=v3 (km /i)。

So the speed of the car is:

×0 in v3 and +0 in v3.

In v3 = ×09,

=6 it (km/h).

The speed of car b is:

In v3, it is -6 =7 (km /i).

Answer: A car travels 6 kilometers per hour, and B car travels 7 kilometers per hour.
