If they are driving directly opposite eachother,
\n" ); document.write( "you can just add their speeds
\n" ); document.write( "Let $\"s\"$ mi/hr = speed of slower car
\n" ); document.write( "Then $\"s+%2B+10\"$ mi/hr = speed of faster car
\n" ); document.write( " $\"1040+=+%28s+%2B+s+%2B+10%29%2A8\"$ mi
\n" ); document.write( " $\"1040+=+%282s%2B+10%29%2A8\"$
\n" ); document.write( " $\"1040+=+16s+%2B+80\"$
\n" ); document.write( " $\"1040+-+80+=+16s\"$
\n" ); document.write( " $\"16s+=+960\"$
\n" ); document.write( " $\"s+=+60\"$
\n" ); document.write( "The speed of the slower car is 60 mi/hr
\n" ); document.write( "check:
\n" ); document.write( " $\"1040+=+%282s%2B+10%29%2A8\"$
\n" ); document.write( " $\"1040+=+%282%2A60%2B+10%29%2A8\"$
\n" ); document.write( " $\"1040+=+130%2A8\"$
\n" ); document.write( " $\"1040+=+1040\"$
\n" ); document.write( "OK
\n" ); document.write( " \n" ); document.write( "

\n" );
