At the beginning of Xiaoshengchu, two cars, A and B, set off at the same time, meet at a distance of 90km, then continue on, and return again at a distance of 65% of the total distance from A.. ...
When we first met, the two cars completed a whole journey together.

When they met for the second time, the two cars completed a whole journey separately, another whole journey together, and another three whole journeys.

Because the speed is constant, the distance traveled is directly proportional to the time spent. Therefore, the time of the second meeting is three times that of the first meeting.

So when we met for the second time, the garage from A was 90×3=270 kilometers.

At this time, it is 65% away from A, so it is back to 1-65%=35%.

Plus a complete journey, the distance traveled is 1+35%= 135% of the distance between the two places.

So the distance between the two places is 270÷ 135%=200 kilometers.

Comprehensive formula: 90×3÷(2-65%)=200 km.
