The passenger car and the freight car leave from a and B and meet each other in 5 hours. The latter two cars run for 3 hours respectively. The passenger car is 180 km away from B and the freight car is 210 km away from a A. B how many kilometers are there? Is that ok? Suppose the speed of the bus is x, the train is 5x + 5Y = 8x + 180, and the train is 5x + 5Y = 8y + 210
The passenger car and the freight car leave from a and B and meet each other in 5 hours. The last two cars run for 3 hours respectively. The passenger car is 180 kilometers away from B and the freight car is 210 kilometers away from A. how many kilometers is the distance between a and B? How to use the equation to solve the problem?
Formula:
(180+210)÷（1-3/5）
=390÷2/5
=975km
Equation:
Let a and B be x km apart
x-3/5x=180+210
2/5x=390
x=975
The passenger car and the freight car leave from a and B respectively. After three hours of meeting, they continue to move forward. After another two hours, the passenger car arrives at B and the freight car stops
There are 95 kilometers away from A. find the distance between the two places
Bus speed: train speed = 3:2
Speed difference = 95 / 5 = 19 km
Therefore, the bus speed is 19 * 3 = 57 km / h
Truck speed = 19 * 2 = 38 km / h
Distance = 57 * 5 = 285km
The passenger car and the freight car leave from a and B respectively. After 3 hours, they meet each other and continue to move forward. After another 2 hours, the passenger car arrives at B. at this time, the freight car is 42 kilometers away from A. find out the distance between the two places
The bus runs for 5 hours, and the meeting time is 3 hours. When the bus runs for 3 / 5 of the whole journey, the truck runs for 2 / 5 of the whole journey. The truck runs for (2 / 5) / 3 = 2 / 15 of the whole journey every hour, 2 / 15 * 5 = 2 / 3 of the whole journey every 5 hours, and 1-2 / 3 = 1 / 3 of the rest of the whole journey. The distance between the two places is 42 / (1 / 3) = 126 km
