At the same time, the passenger and freight cars leave from a and B and meet each other. The distance ratio of the two cars is 5:4. After meeting, the freight cars travel 27 kilometers more per hour than before The bus is still going at the same speed, but the two cars arrive at each other's departure station at the same time. How many kilometers does the bus travel per hour?

At the same time, the passenger and freight cars leave from a and B and meet each other. The distance ratio of the two cars is 5:4. After meeting, the freight cars travel 27 kilometers more per hour than before The bus is still going at the same speed, but the two cars arrive at each other's departure station at the same time. How many kilometers does the bus travel per hour?

Because the time used before and after the meeting is the same, the distance ratio is the speed ratio. The distance ratio is 5:4 when the meeting, and 4:5 after the meeting. Taking the bus as the benchmark, the speed before the meeting is 4 / 5 of the bus, and the speed after the meeting is 5 / 4 of the bus, and the speed change is 27
27/（5/4-4/5)=27/0.45=60
The bus runs 60 kilometers per hour

Passenger and freight cars leave from both places at the same time. When they meet, the distance ratio of the two cars is 5:4
After the meeting, the freight car traveled 27km more per hour than before. The bus still went at the same speed, but the two cars arrived at each other's departure station at the same time?

The bus has been running for 10 hours, so the truck has been running for 10 hours. When meeting, the bus has been running for 5 / (5 + 4) = 5 / 9, the truck has been running for 1-5 / 9 = 4 / 9, the truck has been running for 10 × 5 / 9 = 50 / 9, the truck has been running for (4 / 9) / (50 / 9) = 2 / 25, after meeting, the truck has been running for 5 / 9, the truck has been running for 10-50 / 9 = 40 / 9, every

The two passenger and freight cars leave from a and B at the same time. When they meet, the distance ratio of the two cars is 5:4. After meeting, the freight car is 18 kilometers faster than the passenger car per hour
As a result, the two cars arrived at the other side's departure station at the same time. It is known that the truck has been running for 10 hours. How many kilometers is the distance between a and B?

5+4=9,5÷9=5/9,4÷9=4/9,
Time for two cars to meet: 5 / 9 × 10 = 50 / 9 hours
Time for two cars after meeting: 4 / 9 × 10 = 40 / 9 hours
40 / 9 × 18 ÷ (5 / 9-4 / 9) = 720km
A: the distance between a and B is 720 kilometers

The two passenger and freight cars leave from both places at the same time and meet at 18 kilometers away from the midpoint. It is known that the ratio of the passenger car's journey to the freight car's journey is 8:5 at this time
How many kilometers are there between a and B

Passenger cars travel 18 × 2 = 36 kilometers more than freight cars
8+5=13
The distance between a and B is 36 ÷ (8 / 13-5 / 13) = 156 km
