The distance between a and B is 540 kilometers. The two passenger and freight cars travel from a and B in opposite directions. They meet each other in 6 hours. The speed of the two passenger and freight cars is 5:4. How many kilometers does the bus travel per hour? By the way, I would like to talk about the solution to this problem!

The speed sum is 540 △ 6 = 90 km / h
So the bus speed is 90 × 5 / 9 = 50 km / h
Truck speed 90 × 4 / 9 = 40 km / h
I'm a teacher. Thank you



The distance between the two places is 540 kilometers. A and B cars leave from the two places at the same time. They meet three hours later. It is known that the speed ratio of a and B cars is 5:4. How many kilometers do a and B cars walk each hour?


540 △ 3 = 180 (km) 5 + 4 = 9 A: 180 × 59 = 100 (km) B: 180 × 49 = 80 km) a: A and B travel 100 km and 80 km per hour respectively



The speed ratio of the two vehicles is 8:7. When the two vehicles meet, the truck is still 8 kilometers away from the midpoint of a and B. how many kilometers is the distance between a and B?


When two cars meet, the speed of two cars is proportional to the distance, that is, 8:7; 87 + 8 = 815 for passenger cars; 77 + 8 = 715 for freight cars; 8 × 2 ^ (815 − 715), = 16 ^ 115, = 240 (km); a: the distance between a and B is 240 km
