Question:
bus from the A and B goods from the relatively open, 6 hours later, the bus from the B to have the whole 1 / 8, the midpoint of goods more than 54 km. Known bus line and more than the truck 15 km per hour, and B the distance between the two is how many kilometers?

Answer:
Jiangshan you are counting how ah? If you balance out the equation, then X should be 384 but we

ah check you
bus speed should be (7 / 8) * 384 / 6 = 336 / 6 = 56
vehicle speed (384 / 2 +54) / 6 = (192 +54) / 6 = 246 / 6 = 41

goods should be by the speed of passenger cars is 56-41 = 15, checked reverse is also right in line with the intended title. Therefore, the distance should be ah
384. . .

PS: sorry, no format in place, so that the number of disconnected. Its speed:
(1-1/8) x / 6 km / h
2. 6 hours driving distance of goods: x / 2 +54 km. Its speed:
(x / 2 +54) / 6 km / h
out under the Italian title equation:
(1-1/8) x/6- (x / 2 +54) / 6 = 15
Solution of equation was:
x = 164 km2006-05-22
问题:
客车从甲地，货车从乙地相对开出，6小时后，客车距乙地还有全程的1/8，货车超过中点54千米。已知客车比货车每小时多行15千米，甲乙两地间的路程是多少千米？

回答:
江山你是怎么算的啊？如果按你出的那个方程算，那么X应该是384啊

而且大家验算一下
客车速度应该是（7/8）*384/6=336/6=56
货车的速度是（384/2+54）/6=（192+54）/6=246/6=41

应为客车减货车的速度是56-41=15，验算逆向也正确符合题意。所以距离应该是
384啊。。。

PS：不好意思，格式没放好，让数字断开了。这下看明白了吧

回答:
设两地距离为X千米：
分析：1. 6小时客车行驶的距离为：(1-1/8)x 千米。其速度为：
（1-1/8)x/6 千米/小时
2. 6小时货车行驶的距离为：x/2+54 千米。其速度为：
(x/2+54)/6 千米/小时
根据题意列方程：
（1-1/8)x/6-(x/2+54)/6=15
解方程得：
x=164 千米2006-05-22
