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
At the same time, the passenger car and the freight car go from a and B to each other, and they meet in 5 hours. After meeting, the passenger car goes for another 3 hours to reach B. It is known that the freight car travels 72 hours per hour
How many kilometers are there between a and B?
5 × 72 △ 3 / 8 = 960km
A passenger car and a freight car leave from a and B at the same time and meet each other in 4 hours. If the passenger car runs for 3 hours and the freight car runs for 2 hours,
The two cars are still 11 / 30 apart. When will the bus finish the whole journey?
1-1/4x2-11/30=2/15 2/15x4=8/15
1-8 / 15 = 7 / 15 4 divided by 7 / 15 = 60 / 7 hours
The bus and the truck start from a and B at the same time, and run in opposite directions. They meet in 5 hours. After meeting, the bus reaches B in 3 hours,
The passenger car and the freight car start from a and B at the same time and run in opposite directions. They meet in 5 hours. After meeting, the passenger car reaches B in 3 hours. It is known that the freight car runs 72 kilometers per hour. How many kilometers are there between a and B?
From the title, we can know the distance between the two places as long as we know the speed of the bus
It can be seen from the title that the 3-hour journey from the meeting place to place B takes 5 hours for the freight car. If the speed of the freight car is known, the speed of the passenger car can be calculated as 72 × 5 △ 3 = 120km / h
Then the distance between a and B is 120 × 8 = 960km
I've done it. I really feel it. I haven't used my brain so much for a long time
