When a plane flies into the wind,it can travel 3000km in 6 hours.
\n" ); document.write( "rate = 3000/6 = 500 km/h
\n" ); document.write( "-----------------------------------
\n" ); document.write( "When it flies with the wind, it can travel the same distance in 5 hours.
\n" ); document.write( "rate = 3000/5 = 600 km/h
\n" ); document.write( "-----------------------------------\r
\n" ); document.write( "\n" ); document.write( "Find the rate of the plane in still air and the rate of the wind.
\n" ); document.write( "-----
\n" ); document.write( "Equations:
\n" ); document.write( "p + w = 600 km/h
\n" ); document.write( "p - w = 500 km/h
\n" ); document.write( "------
\n" ); document.write( "Add and solve for \"p\":
\n" ); document.write( "2p = 1100
\n" ); document.write( "p = 550 km/h (rate of the planc in still air)
\n" ); document.write( "---
\n" ); document.write( "Solve for \"w\";
\n" ); document.write( "p + w = 600
\n" ); document.write( "550 + w = 600
\n" ); document.write( "w = 50 km/h (rate of the wind)
\n" ); document.write( "=======================================
