A passenger car travels from A to B in 6 hours, and a truck travels 60 km per hour. Now two cars, passenger and freight, are traveling towards each other from places A and B at the same time. When they meet, the distance traveled by the passenger car is (5/4) that of the truck. Find the distance between places A and B.
