Two cars leave from two places 360 kilometers apart at the same time. They meet three hours later. It is known that the speed ratio of the two cars is 7:5. How many kilometers does the fast car travel per hour No equations!
Speed sum = 360 / 3 = 120 km / h
5+7=12
So the speed of express train is 120 × 7 / 12 = 70 km / h
Station a and station B are 360 km long. An express train and a local train run from two places at the same time. They meet in 3.6 hours. It is known that the speed ratio of fast train and local train is 3:2. How many kilometers does the local train run per hour? Send the process
At 10:00 a.m. and 7:00 B.M., a travels 276 kilometers more than B. if the speed is the same, what is the speed of a and B
The velocity is set as XKM
10x-7x=276
3x=276
x=92

A. B is 546 km away from the two places. The two passenger trains start from the two places at the same time and meet each other in 3 hours. It is known that the speed of car a is three times that of the existing car, and the speed of car a per hour
546 / 3 / (1 + 3)
