When a plane flies with the​ wind, it can travel 1680 miles in 4 hours. When the plane flies in the opposite​ direction, against the​ wind, it takes 5 hours to fly the same distance. Find the rate of the plane in still air and the rate of the wind.\r

\n" ); document.write( "\n" ); document.write( "The rate of the wind is ____ miles per hour.
\n" ); document.write( "==========================================
\n" ); document.write( "Find the 2 groundspeeds, downwind and upwind.
\n" ); document.write( "The plane's airspeed is the average of the 2.
\n" ); document.write( "========
\n" ); document.write( "Windspeed = difference between airspeed and groundspeed.
