翻译：卡尔的汽车一加仑汽油能跑35英里，他的汽车邮箱加满是14加仑汽油．一天，卡尔加满了汽油，驾驶汽车开了350英里，然后又加了8加仑汽油，继续开到他的目的地，当他到达目的地的时候，油箱还剩下半箱汽油，那么这一天卡尔驾驶汽车一共行驶了（ ）英里．
先算耗油，再算路程，先跑了350英里，耗油 $350 \div 35 = 10$ （加仑），剩 $14 - 10 = 4$ （加仑），$+ 8 = 12$ （加仑），到目的地后剩一半，也就是 $14 \div 2 = 7$ （加仑），又用掉 $12 - 7 = 5$ （加仑），所以总路程是 $350 + 5 \times 35 = 525$ （英里）．
