The speed ratio of the passenger car to the freight car is 3:2, and the speed ratio of the passenger car to the freight car is 3:2

The speed ratio of the passenger car to the freight car is 3:2, and the speed ratio of the passenger car to the freight car is 3:2


The bus has traveled 50x2 = 100km more
The distance between the two places is 100x (3 + 2) / (3-2) = 500km



The two passenger and freight cars travel from both sides at the same time. It takes 12 hours for the passenger car to complete the whole journey. The speed ratio of the passenger car to the freight car is 5:3,
How many kilometers per hour does the bus travel 525 kilometers and the truck travel


The speed ratio of passenger cars to freight cars is 5:3, the distance ratio is 5:3, and the time ratio is 3:5
525x3 / 5 = 315km
It takes 12x5 / 3 = 20 hours for the whole journey
The time of meeting is 1 / 12 + 1 / 20 = 1 / 60 + 3 / 60 = 60 / 8 = 15 / 2 hours
Freight car speed 315 △ 15 / 2 = 42 km / h
