s = d/t
\n" ); document.write( "x = airplane speed in still air
\n" ); document.write( "y = wind speed
\n" ); document.write( "---
\n" ); document.write( "against the wind:
\n" ); document.write( "x - y = 715/(2+10/60)
\n" ); document.write( "---
\n" ); document.write( "with the wind:
\n" ); document.write( "x + y = 715/(1+50/60)
\n" ); document.write( "---
