A and B start from a and B at the same time, and run in opposite directions. After 5 hours of meeting, B runs 180 kilometers. If the speed ratio of a and B is 5:6, how many kilometers is the distance between a and B?
A: the distance between a and B is 330 km
When car a reaches 3 / 7 of the whole journey, car B runs 144 kilometers. When car a reaches 7 / 10 of the whole journey, how many kilometers are there between a and B
480km
Party A and Party B drive relatively. When car a drives the whole journey and car B drives 7 / 10, it means that the speed of car B is 7 / 10 of that of car a
So when car a drives to 3 / 7 of the whole journey, car B should drive to 3 / 10 of the whole journey
The total distance is 144 / (3 / 10) = 480km
I hope I can help you
