Let distance to interview be D\r\n" );
document.write( "Then time taken to get to interview = \"D%2F40\"\r\n" );
document.write( "Time taken to return = \"D%2F30\"\r\n" );
document.write( "We then get the following TIME equation: \"matrix%281%2C3%2C+D%2F40%2C+%22=%22%2C+D%2F30+-+1%2F2%29\"\r\n" );
document.write( "3D = 4D - 60 ----- Multiplying by LCD, 120\r\n" );
document.write( "3D - 4D = - 60\r\n" );
document.write( "- D = - 60\r\n" );
document.write( "D, or distance = \"highlight_green%28matrix%281%2C4%2C+%28-+60%29%2F%28-+1%29%2C+%22=%22%2C+60%2C+miles%29%29\"\r\n" );
document.write( "How easy was that?
