\n" ); document.write( "speeds until they are 517.5 mi apart
\n" ); document.write( "\"+517.5+=+%28+54+%2B+61+%29%2At+\"
\n" ); document.write( "\"+517.5+=+115t+\"
\n" ); document.write( "\"+t+=+517.5%2F115+\"
\n" ); document.write( "\"+t+=+4.5+\"
\n" ); document.write( "They will be 517.5 mi apart in 4.5 hrs
\n" ); document.write( "--------------
\n" ); document.write( "check:
\n" ); document.write( "Slower bus:

\n" ); document.write( "\"+d%5B1%5D+=+243+\" mi
\n" ); document.write( "and
\n" ); document.write( "\"+d%5B2%5D+=+61%2A4.5+\"
\n" ); document.write( "\"+d%5B2%5D+=+274.5+\"
\n" ); document.write( "and

\n" ); document.write( "\"+d%5B1%5D+%2B+d%5B2%5D+=+517.5+\"
\n" ); document.write( "which is correct -OK
