（1）若行驶了2.4千米，则收费（）元．

（2）若行驶x千米（x＞3），试用含x的代数式表示应收的车费．

（3）若某人乘坐出租汽车行驶5千米应付多少元？

（4）若某人付费16元，出租汽车最多行驶多少千米？

答案

解：（1）行驶了2.4千米，没有超过起步价规定的3千米，

∴应付8元；

（2）∴3千米内应付费8元，超过3千米的路程为（x﹣3）千米，每千米应付费2元，

应收的车费为8+（x﹣3）×2=2x+2；

答：应收的车费为（2x+2）元．

（3）当x=5时，2x+2=12元，

答：应付费12元；

（4）2x+2=16，解得x=7．

答：某人付费16元，出租汽车最多行驶7千米．
