Let the rate in the city be r. Thus the rate in the open highway is 2r.
\n" ); document.write( "The equation we always use is
\n" ); document.write( "Rate * Time = Distance or
\n" ); document.write( "RT = D
\n" ); document.write( "so we have
\n" ); document.write( "r(1) + 2r(4) = 387
\n" ); document.write( "9r = 387
\n" ); document.write( "r = 43 km/hr
