Two cars leave oppositely from A and B at the same time. Car A travels 85 kilometers per hour, and Car B travels 75 kilometers per hour. After the two cars leave at the same time for 2.5 hours, the distance between the two cars is 20.5 kilometers. How far apart are the places? (calculated in two cases)
