\n" ); document.write( "

Let speed of car be S
\n" );
document.write( "Then speed of plane = 3S
\n" );
document.write( "The following TIME EQUATION is thus formed:
\n" );
document.write( "
\n" );
document.write( "2,880 = 960 + 24S ------- Multiplying by LCD, 3S
\n" );
document.write( "2,880 – 960 = 24S
\n" );
document.write( "1,920 = 24S
\n" );
document.write( "S, or speed of car = , or  km/h
\n" );
document.write( "Speed of plane: 3(80), or  km/h
\n" );
document.write( "You can do the check!!
