\r\n" );
document.write( "When Jane left town P for town Q at 11 am, Mark was 75 km ahead.\r\n" );
document.write( "\r\n" );
document.write( "The difference of their speeds is 120 - 75 = 45 km/h.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, Jane passed Mark in   =  hours, counting from 11 am.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "During this time,    hours, Jane covered the distance of   = 40*5 = 200 km.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "This distance, 200 km, is    of the distance from P to Q, according to the problem.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the whole distance from P to Q is   = 500 km.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the other side, Jane traveled 5 hours (from 11 am to 4 pm) at the speed of 120 km/h -\r\n" );
document.write( "hence, she traveled 5*120 = 600 km.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus we obtained two different values, 500 km and 600 km, for the distance from P to Q.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It tells us that the different parts of the problem are not consistent.\r\n" );
