The passenger and freight cars travel from a and B at the same time. The passenger cars travel 65 kilometers per hour and the freight cars 45 kilometers per hour. After 7 hours, the two cars are in phase How many kilometers between a and B?

The passenger and freight cars travel from a and B at the same time. The passenger cars travel 65 kilometers per hour and the freight cars 45 kilometers per hour. After 7 hours, the two cars are in phase How many kilometers between a and B?


(65+45)×7
=110×7
=770 (km)



The distance between a and B is 216 km. Both passenger and freight cars run from a and B at the same time,
When the two cars meet for the second time, how many kilometers more does the bus travel than the truck?


The total time from departure to the second meeting: 216 × 2 ^ (58 + 50) = 4 (hours)
When the two vehicles meet each other for the second time, the passenger cars travel more than the freight cars: (58-50) × 4 = 32 (km)
