You can put this solution on YOUR website!
lets assume distance travelled = x
\n" ); document.write( "as you know speed = distance /time
\n" ); document.write( "total time taken = x/18 + x/14 = 8\r
\n" ); document.write( "\n" ); document.write( "7x/126 + 9x/126 = 8
\n" ); document.write( "16x/126 = 8
\n" ); document.write( "x = 8*126/16 = 63 miles
\n" ); document.write( "
\n" ); document.write( "
\n" );
