\r\n" );
document.write( "As the problem says in the description, BOTH drivers have the same speed.\r\n" );
document.write( "\r\n" );
document.write( "Let x miles per hour be their common speed.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "First  driver was 240 miles from the finish 3 hours after the start.\r\n" );
document.write( "\r\n" );
document.write( "Second driver was 300 miles from the finish 2.5 hours after the start.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that first driver in 3 hours traveled 60 miles farther,\r\n" );
document.write( "than the second driver traveled in 2.5 hours with the same speed.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the speed of the first driver was 60/0.5 = 120 miles per hour.\r\n" );
document.write( "\r\n" );
document.write( "And since both drivers have THE SAME SPEED, we have this\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  Each driver traveled at the speed of 120 miles per hour.\r\n" );
