The distance between the two places is 260 km. The two vehicles leave each other and meet each other in 3.5 hours. The speed ratio of the two vehicles is 2:3, and the speed of the two vehicles is calculated Fast~~~~~~
The speed of a is X
The speed of vehicle B is 1.5x (obtained from the speed ratio of vehicle a and vehicle B is 2:3)
(X+1.5X)×3.5=260
X = 208 / 7 is about 30 km / h
Party A and Party B are facing each other. They met when they were 1.5 hours old. Car a still has two hours to get to place B, and car B still has nine eighths of an hour to get to place A. AB is 210 kilometers away,
The problem is not rigorous enough. If you ask, you probably know that you want to say that they start at the same time, but you don't know whether a starts from a and B starts from B. so you can only use the general situation, that is, you don't know where they start, but this problem can't be solved, so if there is a solution, you can only start from a and B
The two cars are 84 kilometers away from each other at the same time. The speed of car a is 20 kilometers per hour faster than that of car B. half an hour later, the two cars meet. What's the speed of the two cars?
Let a speed X
0.5（x+x-20）=84
x-10=84
x=84+10
x=94
B speed 94-20 = 74 km / h
