The distance between a and B is 360 km. A bus and a truck leave from the two places and meet each other after 5 hours Given that the ratio of passenger cars to freight cars is 4:5, what are the speeds of passenger cars and freight cars? Given that the speed ratio of passenger cars to freight cars is 4:5, what are the speeds of passenger cars and freight cars?

The distance between a and B is 360 km. A bus and a truck leave from the two places and meet each other after 5 hours Given that the ratio of passenger cars to freight cars is 4:5, what are the speeds of passenger cars and freight cars? Given that the speed ratio of passenger cars to freight cars is 4:5, what are the speeds of passenger cars and freight cars?

360÷5=72
72×4／9=32
72×5／9=40

The distance between a and B is 360 km. The passenger cars and freight cars depart from a to B at the same time. The freight cars travel 60 km per hour, the passenger cars 40 km per hour, and the freight cars 40 km per hour
It's 40 kilometers per hour. It takes half an hour for the lorry to load goods when it arrives at the second place, and then it returns to the first place at the same speed. How long does it take for the lorry to meet the bus after it starts from the second place?

How long does it take for the truck to arrive at site B
360 △ 60 = 6 (hours)
When the lorry returned to Jiadi at the same speed, the bus went
40 × (6 + 0.5) = 260 (km)
Distance between two cars
360-260 = 100 (km)
How long does it take for the truck to meet the bus after departure from B
100 ÷ (60 + 40) = 1 (hour)

The distance between a and B is 270 km. A freight car and a passenger car drive from the two places at the same time and meet at 10:3. It is known that the speed ratio of the freight car and the passenger car is 4:5. How many kilometers does the passenger car travel per hour?

The speed sum of freight cars and passenger cars is 360 △ 4.5 = 80 km / h
And then it's distributed proportionally
80 × 7 / (7 + 9) = 35 km / h
The bus runs 35 × 9 / 7 per hour = 45 km
