The distance between the two places is 455km. A and B cars leave from the two places at the same time and run in opposite directions. After 3.5 hours, they meet. A car travels 68km per hour, B car travels how many km per hour?
455 △ 3.5-68 = 130-68 = 62 (km) a: car B travels 62 km per hour
2. The distance between a and B is 360 km, and two cars leave each other at the same time. After 3 hours, the ratio of the distance traveled and the rest is 3:2
How many hours will it take for the two cars to meet at this speed
It's going to take x hours
yes:
3：（3＋2）＝3：（3＋x）
So: x = 2
Two more hours
Car a and car B run from a and B at the same time. They meet in 8 hours and continue to drive after meeting. After 3 hours, they are 360 kilometers apart. How many kilometers are there between a and B?
A: the distance between a and B is 960 km
A and B, which are 360 km apart, set out at the same time and run in opposite directions. After 4.5 hours, they met. They have been driving 45 km per hour, and one car runs more than one hour
Less kilometers?
360÷4.5 - 45= 80- 45 = 35（km/h）
A: 35 kilometers per hour
