\n" ); document.write( "

Let speed of jet, be S
\n" );
document.write( "Then speed of propeller plane = S – 160
\n" );
document.write( "We then get: 
\n" );
document.write( "Multiply by LCD, S(S - 160), and solve for S: the speed of the jet. Then calculate: S - 160 for the speed of the propeller plane.
\n" );
document.write( "You should get: jet's, and propeller plane's speeds as: , and , respectively \n" );
document.write( "

\n" );
