小红和小强同时从家里出发相向而行,小红每分钟走52米,小强每分钟走70米,两人在途中的A处相遇.若小红提前4分钟出发,且速度不变,小强每分钟走90米,则两人仍在A处相遇,小红和小强的家相距多少米?
A: are 1464 meters apart
With the second yuan A equation set, A place with little red house apart X m, little red house and jack Bauer home Y m, are: 1. X = (Y divided by 52-X) divided by 70, 2. (52)-4 X divided by = = (Y-X) divided by 90 rection can get: 122 X = 52 Y, 142 X-52 Y = 18720 solution binary A equation can get: X = 624, Y = 1464
答： 相距1464米
用二元一次方程解，设A处与小红家相距X米，小红家和小强家相距Y米，可得：1. X除以52=（Y-X）除以70， 2. （X除以52） -4==（Y-X）除以90 化简可得：122X=52Y， 142X-52Y=18720 解二元一次方程可得：X=624，Y=1464

2·甲乙两人同时从跑道相向而行，经过6分钟相遇，两人据需走，4分钟后甲回到了起点，乙距离起点还有300米，求跑道全长。
A b two people at the same time from the runway at and do it, after six minutes, two people to meet according to walk, four minutes after the start point b a return to the starting point and 300 m distance, and the runway.
The answer a total go 6 + 4 = 10 minutes, go all the way,
So meet, b's journey is equivalent to a walk four minutes;
So the speed and a second faster than is: so
Set a 6 X speed is, the b speed is 4 X,
For 10 minutes, there go just a whole journey, b and 300 m to go all the way,
So there are:
10 * 6 X = 10 * 4 X + 300
Given the X = 15
So a speed is 15 * 6 = 90 m/min
So the runway length is 10 * 90 = 900 m
答案 甲一共走了6+4=10分钟，走完全程；
所以相遇时，乙走的路程相当于甲走4分钟；
所以乙的速度和甲的速度比是：6:4
设甲速度是6X，则乙速度是4X，
因为一共走了10分钟，甲刚好走完全程，乙还有300米走完全程；
因此有：
10*6X=10*4X+300
解得 X=15
所以甲速度是15*6=90米/分钟
所以跑道全长是10*90=900米

(a)How many apples did he sell altogether?
(b)How many fruits did he have at first?
一个水果商有若干水果，水果中的3/5是苹果剩下的是桔子，他卖了苹果的2/3桔子的1/4。他仍有苹果和桔子40个，
问他总共卖了多少苹果
问他原先总共有多少水果
总共有水果：
40/{3/5 *(1-2/3) +(1-3/5)*(1-1/4)}=80
苹果有：80*3/5＝48
卖了的苹果：48*2/3=32
所以
（a）32
（b）80
