In a triathlon, Jenny swim for one hour, bike for 1.75 hours, and ran for one hour. Her average biking speed was two times her average running speed, and her average running speed with eight times her average swimming speed. The total distance of the triathlon was 55.5 km. Calculate Jenny's average swiming speed in kilometers per hour.

Let swimming speed be S
\n" );
document.write( "Then running speed = 8S	
\n" );
document.write( "Biking speed = 2(8S), or 16S
\n" );
document.write( "We then get the following DISTANCE equation: S + 8S + 1.75(16S) = 55.5	
\n" );
document.write( "Solve for S, the swimming speed and you should get: 
\n" );
document.write( "Very, very simple....nothing COMPLEX, regardless of how complex some people may make it! \n" );

\n" );
