A certain truck traveling at 55 miles per hour gets 4.5 miles per gallon of diesel fuel consumed. Traveling at 60 miles per hour, the truck gets only 3.5 miles per gallon . On a 500-mile trip, if the truck used a total of 120 gallons of diesel fuel and traveled part of the trip at 55 miles per hour and the rest at 60 miles per hour, how many miles didit travel at 55 miles per hour? 某卡车，以 55英里/每小时 速度行驶，消耗柴油 4.5英里/加仑。以 60英里/小时 速度行驶,消耗柴油 3.5英里/加仑。 在一个500英里的行程中,如果卡车把120加仑的柴油用光，一部分路程以每小时55英里行驶,其余部分以每小时60英里行驶，它以55英里每小时行驶了多少英里? 设55m/h行驶了a miles，那么60m/h行驶500-a a/4.5+(500-a)/3.5=120 代入选项 方便计算

单位复杂题，很多时候都会出现数据无用情况，这种题目的解题思路是抓住单位，消除同样单位

无语了，how many miles did it travel at 55 miles per hour, 看成了how many miles didn't travel at 55 miles per hour. 能不能把题目格式弄好点

设用55m/h走了x miles，用60m/h走了y miles； x+y=500 x/4.5+y/3.5=120 y=140，x=360 要搞清楚逻辑关系，速度*时间=路程；路程/单位油耗=总油耗

为啥路程/单位油耗=总油耗？不应该是乘吗？
