Party A and Party B travel from AB to each other at the same time. After meeting for 5 hours, Party A will travel for 4 hours to arrive at place B. how many hours will Party B have to travel to arrive at place a? Lie equation Suppose X

Party A and Party B travel from AB to each other at the same time. After meeting for 5 hours, Party A will travel for 4 hours to arrive at place B. how many hours will Party B have to travel to arrive at place a? Lie equation Suppose X

Equation method
When they met, Party A and Party B each took five hours, and the journey before Party A and Party B met only four hours,
It shows that the time ratio of Party A and Party B is 4:5
According to this ratio, the equation is given. Let B arrive at a in X hours
4：5=5：X
4X=5×5
X=6.25
A: B will take another 6.25 hours to arrive at a

A and B set out at the same time, facing each other. When a arrives at B, B will return to a immediately. How far is the meeting place from a
A. The distance between B and B is 216 km. Party A and B are in a and B respectively. The speed of a is 15 km / h, and that of B is 12 km / h

(the solution of the equation is at the end) there are two imprecise answers to this question (strictly speaking, there are countless), but if you read this question carefully, what you should ask is the second time that Party A and Party B met on the way back. When they met for the second time, Party A and Party B combined three distances between a and B, and the meeting time was 216 × 3 ^ (15 +...)

It took 4 hours for a to go from a to B, and 10 hours for B to go from B to A. how many hours did a and B meet each other?

1÷（1/4+1/10）=40/14=20/7

There are two teams, team a and team B. team a has 28 cars and team B has 11 cars. After the deployment of the vehicles of the two teams, there are still some additional problems···
3 / 2 of the number of cars in team B is just 75% of the number of cars in team A. how are the cars allocated?

The two teams have a total of 39 vehicles: 28 + 11
After deployment, the ratio of a and B vehicles is 3 / 2:75% = 2:1
After deployment, team a has 26 cars: 39 ÷ (2 + 1) × 2
Team a: 28-26 = 2
Hope to help you!
If you don't understand, please ask. I wish you progress in your study!
Can it solve your problem?

Party A and Party B set out from two places 16 kilometers apart at the same time. If they travel in opposite directions for one hour, they meet and travel in the same direction for four hours. Party A can catch up with Party B in solving the quadratic equation of speed of Party A and Party B

Set a x km / h
B y
16=x+y
4x-4y=16
have to
x=10
y=6
A 10 km / h
B 6 km / h
