x = speed in still air
\n" ); document.write( "y = wind speed = 40 mph
\n" ); document.write( "---
\n" ); document.write( "x + y = 350
\n" ); document.write( "x + 40 = 350
\n" ); document.write( "x = 310
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "x = speed in still air = 310 mph
