The passenger car and the freight car leave from station a and station B at the same time. The passenger car travels 54 kilometers per hour and the freight car 48 kilometers per hour. After the two cars meet, they continue to move forward at the original speed. The passenger car returns immediately after arriving at station B, and the freight car also returns immediately after arriving at station A. when the two cars meet again, the passenger car travels 216 kilometers more than the freight car

The passenger car and the freight car leave from station a and station B at the same time. The passenger car travels 54 kilometers per hour and the freight car 48 kilometers per hour. After the two cars meet, they continue to move forward at the original speed. The passenger car returns immediately after arriving at station B, and the freight car also returns immediately after arriving at station A. when the two cars meet again, the passenger car travels 216 kilometers more than the freight car

The second meeting time of the two trains is: 216 △ 54-48 = 216 △ 6 = 36 (hours). The distance between the two stations is: (54 + 48) × 36 △ 3 = 102 × 36 △ 3 = 1224 (kilometers). A: the distance between the two stations is 1224 kilometers

When two cars run from both sides at the same time, the passenger car runs 54km per hour and the freight car 45 km per hour. When they meet, the passenger car runs 6km more than the freight car
How many kilometers are there between a and B

6/（54-45）=2/3 2/3*（54+45）=66

The passenger and freight cars leave from a and B at the same time. The passenger cars travel 60 km per hour and the freight cars 54 km per hour. The two cars meet at 7.5 km from the midpoint,
Use elementary school simple equation solution!

What do you want? The distance between a and B?
60-54 = 6 (km) the speed of passenger cars is 6 km / h faster than that of freight cars
When 7.5 × 2 = 15 (km), the bus travels 15 km more than the truck
15 △ 6 = 2.5 (hours) meeting time
(60 + 54) × 2.5 = 285 (km) distance between a and B

Passenger cars and freight cars run from a and B at the same time. Passenger cars run 50km per hour and freight cars 45km per hour. After 4 hours, how many kilometers are there between a and B? How many parts of the whole journey does the bus travel?

(50 + 45) × 4, = 95 × 4, = 380 (km); 50 × 4 ／ 380, = 200 ／ 380, = 1019; answer: the distance between a and B is 380 km, and the bus is 1019
