The railway between station a and station B is 660 km long, and a passenger train runs from station a to station B at the same time After solving the equation, I will add 50 points online The railway between station a and station B is 660 km long. A passenger train runs from station a to station B, and a freight train runs from station B to station A. it meets four hours later. It is known that the speed of the passenger train is 6 / 5 times that of the freight train. How many kilometers do the passenger train and the freight train travel per hour? (solved by equation)
If the speed of freight car is x, the speed of passenger car is 6-5x
x*4+x*6\5*4=660 x=75
Then 75 * 4 = 300 for freight cars and 660-300 = 360 for passenger cars
The railway between station a and station B is 460 km long. A passenger train runs from station a to station B, and a freight train runs from station B to station a, passing two trains in four hours
Meet each other. How many kilometers does the bus travel per hour and the truck travel per hour
460-4 * 60 = 220km
220 / 4 = 55 km / h
So the truck goes 55 kilometers an hour
The railway between station a and station B is 660 km long. A passenger train runs from station a to station B, and a freight train runs from station B to station a,
After 4 hours meeting, how many kilometers does the passenger car travel per hour and the freight car travel per hour
Set up freight cars to travel x kilometers per hour
4（x+90)=660
x+90=165
x=75
The railway between station a and station B is 460 km long. A passenger train runs from station a to station B, and a freight train runs from station B to station a, after 4 hours
When the two cars meet, it is known that the passenger car travels 60 kilometers per hour, and the freight car, (using equation solution)
The freight car travels x kilometers per hour
4(x+60)=460
x+60=115
x=115-60
x=55
The freight car travels 55 kilometers per hour
