我的算法是：
去W的车是30000辆,但它的人数是去Z的两倍,所以要进行比较时,要对等的比较.所以如果把去W的人数减半的话,就是同口径相比了,即：
（30000/2）：1.5=x：1.2
15000:1.5=x：1.2
x=（15000*1.2）/1.5
x=12000

Number of vehicles going to W = 30,000; there are more people than cars, so commuters going to W = 30000*1.2. Commuters going to Z = 30000*1.2/2=18,000. Number of vehicles going to Z = 18000/1.5 = 12,000.
