The distance between a and B is 550 km. The fast train and the slow train leave from a and B at the same time. They meet five hours later. It is known that the speed ratio of the fast train and the slow train is 6:5
How many kilometers per hour is the express train faster than the local train?


550/5=110
Idle speed: (110 / (6 + 5)) * 5 = 50
Express speed: (110 / (6 + 5)) * 6 = 60
60-50=10
10 kilometers per hour



A. B is 550 kilometers away from each other. A and B leave a and B at the same time and meet each other after 5 hours. It is known that the speed ratio of a and B is 6:5. How many kilometers does a and B travel per hour?


Let B's speed be x km / h. according to the equation, we can get that (x + 65x) × 5 = 550 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 11x = 550, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 50; a's speed is



A fast train and a slow train leave from station a and B at the same time and meet at 58 km away from the midpoint. It is known that the speed ratio of fast train and slow train is 3:2. How many km is the distance between station a and station B?


Hello
When the speed ratio is 3:2, the distance ratio is 3:2, the distance of fast train is 3 / 5 of the total distance, and the distance of slow train is 2 / 5 of the total distance,
The meeting at 58 km from the midpoint indicates that the express train is more than 58 km more than half of the total distance, while the local train is less than 58 km less than half of the total distance,
The distance difference between the two cars is 58 + 58
So: the total distance is (58 + 58) / (3 / 5-2 / 5) = 580km
Hope to help you!
