The passenger car and the freight car run from a and B at the same time. They meet each other in five hours. After meeting, the passenger car goes to B in three hours. It is known that the freight car travels 63 kilometers per hour, and how many kilometers per hour does the passenger car travel?

63 × 5 ／ 3, = 315 ／ 3, = 105 (km), answer: the bus travels 105 km per hour

Buses and trucks travel from two places 852km apart and face each other at the same time. When they meet, the distance of buses is 189km less than twice that of trucks. How many kilometers do buses and trucks travel?

Suppose the freight car runs for X km, then the passenger car runs for 2x-189 km, x + 2x-189 = 852, & nbsp; & nbsp; & nbsp; & nbsp; 3x = 852 + 189, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 3x = 1041, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 347; the passenger car runs for 2 × 347-189 = 505 (km); a: the passenger car runs for 505 km, and the freight car runs for 347 km
