When two cars go from a to B, car a travels 120 km per hour. When car B travels 200 km more, car a travels 40% of the whole journey. How many km is it from a to B?

When two cars go from a to B, car a travels 120 km per hour. When car B travels 200 km more, car a travels 40% of the whole journey. How many km is it from a to B?

When car B travels more than 200 km, is it missing

Two cars drive from a to B at the same time. The speed of a is 2 / 3 of that of B. when B travels 200 kilometers more than a, car a just runs 40% of the whole journey
How many kilometers apart

Let the distance be x km and the velocity of B be u
40%x/（2u/3）=(40%x+200)/u
The velocity is about 1000 km
