\r\n" );
document.write( "\r\n" );
document.write( "By the definition, displacement is the distance between the starting and ending point.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In this case, this distance is 190 - 30 = 160 meters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  The displacement is 160 meters in this case.\r\n" );
