\"4%2A%28B+%2B+20%29%2B+4%2AB+=+400\".
\n" ); document.write( "\"B+%2B+20+%2B+B+=+100\", after dividing both sides by 4.
\n" ); document.write( "\"2B+=+80\",
\n" ); document.write( "\"B+=+40\"miles per hour, the speed of B.
\n" ); document.write( "\"A+=+60\"miles per hour, the speed of A.
\n" ); document.write( "
