1·The little red and jack Bauer and mutually leave home and do, little red every minute walk 52 meters per minute, jack Bauer walked 70 meters, two people in A place of meeting. If the little red four minutes in advance, and the speed of the same, jack Bauer every minute walked 90 meters, the two people who still in A place to meet, little red and jack Bauer home how many meters apart?
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 14 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 = 14
答: 相距14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=14

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

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
