$\"d\"$ = distance the faster one travells
\n" ); document.write( " $\"t\"$ = time to get 69 miles apart
\n" ); document.write( "(1) $\"d+=+47t\"$
\n" ); document.write( " $\"d+-+69+=+32t\"$
\n" ); document.write( "(2) $\"d+=+32t+%2B+69\"$
\n" ); document.write( "Set $\"d\"$ in (1) = $\"d\"$ in (2)
\n" ); document.write( " $\"47t+=+32t+%2B+69\"$
\n" ); document.write( " $\"15t+=+69\"$
\n" ); document.write( " $\"t+=+4.6\"$ hrs
\n" ); document.write( " $\".6%2A60+=+36\"$
\n" ); document.write( "In 4 hours and 36 minutes they will be 69 mi apart \n" ); document.write( "
