Rebecca, \"1%2F30\"
\n" ); document.write( "Owen, \"1%2F40\"
\n" ); document.write( "Unit is \"DRIVEWAY%2FMINUTES\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let time t be while Rebecca helps to finish with Owen.\r
\n" ); document.write( "\n" ); document.write( "\"%281%2F40%29%2A8%2B%281%2F30%2B1%2F40%29%2At=2\"---------The equal to 2 is for the requested, \"two driveways\". Solve for t.
