The speed of a freight car is 95% of that of a passenger car. Two cars are driving from two places at the same time. They meet 8 kilometers away from the midpoint to find the distance between the two places! We need formula, formula, not equation, not equation! And we need to write the truth, write the truth!
When we meet, the express train has more lines than the local train: 8 × 2 = 16 (km)
Bus: 16 (1-95%) = 320 (km)
Freight cars: 320 × 95% = 304 (km)
Distance between the two places: 320 + 304 = 624 (km)
The speed of a freight car is 92% of that of a passenger car. At the same time, two cars leave from two places and meet at a distance of 8km from the midpoint to find the distance between the two places
When two cars meet, the proportion of trucks driving the whole journey is: 1 / (1 + 90%) * 90% = 9 / 19
Then the ratio of the meeting place to the midpoint is: 1 / 2-9 / 19 = 1 / 38
If you meet 8 km from the midpoint, the distance between the two places is 8 / (1 / 38) = 304 (km)
The distance between a and B is 2250 km. The passenger cars and freight cars leave at the same time and run in opposite directions. The freight cars run 70 km per hour, and the passenger cars 180 km per hour. How long does it take for the two cars
2250/（70+180）=9
The two cars met in nine hours
The distance between a and B is 480 km. A bus travels 90 km per hour from a to B, and a truck travels 70 km per hour from B to a at the same time
MI. After a few hours, the two cars meet?
After 480 (90 + 70) = 3 hours
