\n" ); document.write( "

Let slower airplane's speed, be S
\n" );
document.write( "Then faster airplane's speed = S + 97
\n" );
document.write( "We then get the following DISTANCE equation: 8S + 8(S + 97) = 12,344
\n" );
document.write( "8S + 8S + 8(97) = 12,344 
\n" );
document.write( "16S = 12,344 - 8(97)
\n" );
document.write( "Speed of slower airplane, or 
\n" );
document.write( "Now, add 97 to the slower speed to get the faster! \n" );
document.write( "

\n" );
