The passenger car and the freight car run from a and B at the same time. They meet each other in five hours. After meeting, the passenger car goes to B in three hours. It is known that the freight car travels 63 kilometers per hour, and how many kilometers per hour does the passenger car travel?

The passenger car and the freight car run from a and B at the same time. They meet each other in five hours. After meeting, the passenger car goes to B in three hours. It is known that the freight car travels 63 kilometers per hour, and how many kilometers per hour does the passenger car travel?


63 × 5 / 3, = 315 / 3, = 105 (km), answer: the bus travels 105 km per hour



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



A passenger car and a freight car are running from a and B at the same time. The speed of the passenger car is 60 km / h,
It's 40 km / h. After the two cars meet, the bus will continue to drive for 4 hours before it arrives at land A. how many kilometers is the distance between the two places?


Suppose the distance between a and B is x km
40/﹙60+40﹚·x=60×4
x=600



The passenger cars and freight cars start from both places at the same time and run in opposite directions. The speed of freight cars is 60 km / h, and that of passenger cars is 80 km / h,
On the way, the bus broke down and continued to drive for 1.5 hours. As a result, the bus and the truck met at the midpoint of the two places. How many kilometers are there between a and B?


Let the running time of freight cars be t
80(T—1.5)=60T
T=0.6
Distance: 2x60xo. 6 = 72
