If a plane can travel 490 mph with wind and 430 mph against the wind,
\n" ); document.write( " find the speed of the plane without a wind and the speed of the wind.
\n" ); document.write( ":
\n" ); document.write( "Let s = speed of plane in still air
\n" ); document.write( "Let w = speed of the wind
\n" ); document.write( ":
\n" ); document.write( "Two simple equations
\n" ); document.write( "s + w = 490
\n" ); document.write( "s - w = 430
\n" ); document.write( "--------------adding eliminates w, find s
\n" ); document.write( "2s = 920
\n" ); document.write( "s = \"920%2F2\"
\n" ); document.write( "s = 460 mph in still air
\n" ); document.write( ":
\n" ); document.write( "I'll let you find the speed of the wind\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
