A and B go from a to B at the same time. When a goes to B, they immediately return and meet B 32 kilometers away. The speed ratio of a and B is 5:4. How many kilometers did B travel when they met?

If the distance is set as X km, there are: (x + 32): (x-32) = 5:4; 5x-160 = 4x + 128; X = 288; so line B 288-32 = 256 km. Hello, I'm glad to answer for you. Skyhunter 002 will answer for you.

Math problem: simplify the following comparison
3.05 to 3 / 4
15 to 3 / 4
One centimeter is better than 300 kilometers
One in three to seven in 18
78 0
25 to 1
Six out of seven to nine out of 14
2 / 3 vs 0.75
There is also a practical problem
The number of new students enrolled in Yucai primary school this year is 1.2 times that of last year

3.05 vs 3 / 4 = 3.05:0.75 = 305:75 = 61:15
15:3 / 4 = 15:0.75 = 20:1
1cm to 300km = 1:30000000
1 / 3 to 7 / 18 = 6 / 18:7 / 18 = 6:7
26 vs. 0.78 = 26:78 = 1:3
25 to 1 = 1:4
6 out of 7 to 9 out of 14 = 12 / 14:9 / 14 = 4:3
75 = 8:9
The number of new students enrolled in Yucai primary school this year is 1.2 times that of last year
1.2:1
=6:5
A: 6:5

Hurry, simplify
a＾6－a＾6
__ ÷ (a＾4＋b＾4＋a＾2b＾2)

Among them It means that it's a score
A ＾ n is the nth power of A

How to simplify this math problem
X = 2^Y-3 +4
How to make it y = form

X-4=2^(Y-3)
log2(X-4)=Y-3
Y=log2(X-4)+3

Simplification
X(2x-7)=-49/8

Reduction: 2x & # 178; - 7x + 49 / 8 = 0, de denominator: 16x & # 178; - 56x + 49 = 0 = = >: 4 * 4x & # 178; - 2 * 4 * 7x + 7 * 7 = 0, in fact, (ax-b) &# 178; = a & # 178; X & # 178; - 2abx + B & # 178; or cross decomposition = = > | 4x - 7 | 4x - 7 | so the original formula = (4x-7) &# 178; = 0

Please help me solve the following math problem
Xiaoxiao drinks a bottle of juice in four times. For the first time, he drinks 1 / 6 of a bottle of juice and then fills it with water; for the second time, he drinks 2 / 3 of a bottle and then fills it with water; for the third time, he drinks half a bottle and then fills it with water; for the fourth time, he drinks it all in one gulp. Does Xiaoxiao drink more juice or more water? Why?

Water 1 / 6 + 2 / 3 + 1 / 2 = 4 / 3 bottles
1 bottle of fruit juice
4/3>1
Plenty of water

In the multiplication formula. Green grass ·. Red flowers =. Bright spring, Chinese characters represent non-zero numbers, different Chinese characters represent different numbers, then. Bright spring represents the smallest number of four digits______ ．

There are 9 Chinese characters, no 0, so 9 Chinese characters correspond to 1 ~ 9, 9 numbers; the minimum requirement, then "flower" and "grass" we can only take 1 and 2; according to the sum of the two numbers, the smaller the difference, the larger the product, we choose "flower" as 1, "grass" is 2; "spring" can only take 3 or 4; "grass green,. Flower red,. Spring bright

Party A and Party B go to the railway station from their unit. They start along the same route. Party A travels 20 kilometers per hour by bike and Party B travels 30 kilometers per hour by car. As a result, Party A arrives at the railway station one twelfth of an hour later than Party B. how many kilometers are there from the unit to the railway station?

Follow up questions
Party A and Party B set out at the same time. When Party B arrives, it will travel 20 × 1 / 12 = 5 / 3 kilometers more than Party A
Catch up time 5 / 3 ÷ (30-20) = 1 / 6 hours
Total length 1 / 6 × 30 = 5km

The 260 meter long train is running at the speed of 16 meters per second. It took 48 seconds for him to pass through a tunnel. How long is the tunnel?

If this tunnel has x meters, then (260 + x) / 16 = 48, x = 508 meters
