\r\n" );
document.write( "At 5:37 AM,  train A is  40 mph x 12 minutes = 40 mph x 0.2 of an hour = 8 miles ahead train B,\r\n" );
document.write( "and the rate of approaching train B to train A is  60-40 = 20 mph.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, train B will catch train A in  \"8%2F20\" = \"24%2F60\" = 24 minutes.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the catching time is 5:37 AM plus 24 minutes, which is  6:01 AM.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  The catching time is  6:01 AM.\r\n" );
