初一一题不等式应用!come on~Just you~I need you to help me~
1:上海市出租汽车的收费标准是:5千米之内起步价10.8元,往后每增加1千米增收1.2元.现从A地到B地共支出车费24元,如果从A到B先步行460米,然后乘车也是24元,求从AB中点C到B地需支付多少元车费?
用不等式怎么做?千万要带我讲详细~求求各位了,每一步是怎么来的麻烦在边上注明~Ok~~~

现设AB之间距离为x千米
24-1.2≤10.8+(x-5)×1.2≤24
24-1.2≤10.8+(x-5-0.46)×1.2≤24
得出15.46≤x≤16
在计算∣x/2-5∣ 即计算x/2-5的绝对值
计算得2.73≤x/2-5≤3
则取3,因为无论是否达到3km,只要超过了2km,就自动记为3km了
然后计算3×1.2+10.8=14.4
不确定计算的对,但思路应该是这样的
