\n" ); document.write( "A biker decided to cover the distance of 120 km at a certain speed. However, he actually went 6 km/h slower so he arrived at his destination 1 hour later than he wanted to. What was the actual speed of the biker?
\n" ); document.write( "PS:If x is the actual speed of the biker, then what is the equation?
\n" ); document.write( "

Since actual speed was x, then planned speed was: x + 6
\n" );
document.write( "Time taken to cover distance at actual speed: 
\n" );
document.write( "Time it would’ve taken to cover distance at planned speed: 
\n" );
document.write( "The following TIME equation is thus formed: 
\n" );
document.write( "120(x + 6) = 120x + x(x + 6) -------- Multiplying by LCD, x(x + 6) 
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( "(x - 24)(x + 30) = 0
\n" );
document.write( "x, or ACTUAL speed was:          OR        x = - 30 (ignore) \n" );
document.write( "

\n" );
