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
