A fast train and a slow train leave from station a and station B at the same time and meet at 5 km away from the midpoint. It is known that the speed ratio of fast train and slow train is 3:2. How many kilometers are there between station a and station B?
The speed ratio of the fast train to the slow train is 3:2, and their distance is 3:2. The distance between the fast train and the slow train is 35 km and 25 km respectively. 5 × 2 ^ (35 − 25) = 10 ^ 15, = 50 km. A: the distance between the two stations is 50 km
The speed of the car is 4 / 7 of the speed of the train. The two cars are facing each other from both places at the same time. They meet 15 kilometers away from the midpoint
The speed of the car is 4 / 7 of the speed of the train. The two cars run from two places at the same time and meet at 15 kilometers away from the midpoint. How many kilometers did the train travel?
Then the train started
15 * 2 ÷ (1-4 / 7) = 70 km
The speed of a car is 47 times that of a train. Two cars are running from two places at the same time, and they meet at a distance of 15 kilometers from the midpoint. How many kilometers does the train travel?
The distance of the whole journey: 15 △ 74 + 7-12, = 15 △ 322, = 110 (km), the distance of the train: 110 × 711 = 70 (km). A: at this time, the train runs 70 km
