Assuming they started from the same place @ the same time then:
\n" ); document.write( "516t-420t=4,680
\n" ); document.write( "96t=4,680
\n" ); document.write( "t=4,680/96
\n" ); document.write( "t=48.75 hours after they leave they will be 4,680 mileas apart.
\n" ); document.write( "Proof:
\n" ); document.write( "516*48.75-420*48.75=4,680
\n" ); document.write( "25,155-20,475=4,680
\n" ); document.write( "4,680=4,680
\n" ); document.write( "
\n" ); document.write( "
