document.write( "Question 1073138: Two train stations are 1250 km apart. At midnight, a passenger train and a freight train leave these stations and start towards each other. The passenger train travels 30km/h faster than the freight train, but the passenger train stops for one hour while the freight train travels non-stop. The two trains pass each other at 5:00. Find the rate of each train. \n" ); document.write( "
