\r\n" );
document.write( "Without any calculations, it is clear that the car and the lorry will spend the same time from the start moment \r\n" );
document.write( "to the moment they meet each other.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the lorry will cover   of the distance, which the car will cover.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, if x is the distance under the question,  then\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "x +  = 450\r\n" );
document.write( "\r\n" );
document.write( " = 450\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "x =  = 90*3 = 270.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  The car will cover  270 kilometers, before it meet the lorry.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Check.   270 +  = 270 + 180 = 450 kilometers.   ! Correct !\r\n" );
