[計量] 一題計量
If the total number of commuters to County W is twice
the number to Country Z, and if the average number of
vehicles that transport commuters daily to County W is
30,000, what is the apporximate average number of vechicles
that transport commuters daily to County Z?
答案為 12,000
可是我看不太懂題目要求甚麼
也不會算> <"(一開始還覺的會不會是30000除2)
謝謝大家
