Two trains are now 150 miles apart,
\r\n" );
document.write( "So Distance = 150
the westbound train traveling twice as fast as
\n" ); document.write( "the eastbound train.
\r\n" );
document.write( "So let the eastbound train's rate is r.\r\n" );
document.write( "Then the westbound train's rate is 2r.\r\n" );
document.write( "Their approach rate is the sum of their rates, 3r
\r\n" );
document.write( "So \"RATE+=+3r\"
the trains will crash in 1-1/4 hours.
So \"TIME+=+1%261%2F4\"\r\n" );
document.write( "DISTANCE = (RATE)(TIME)\r\n" );
document.write( "    \"125+=+%283r%29%281%261%2F4%29\"\r\n" );
document.write( "    \"125+=+%283r%29%285%2F4%29\"\r\n" );
document.write( "    \"125+=+15r%2F4\"\r\n" );
document.write( "    \"500+=+15r\"\r\n" );
document.write( "    \"33%261%2F3+=+r\"\r\n" );
document.write( "\r\n" );
document.write( "The eastbound train's speed = r = 33 1/3 mph\r\n" );
document.write( "The westbound train's speed = 3r = 100 mph \r\n" );
document.write( " \r\n" );
