Partially right!! I'm assuming they started from the same point, as opposed to a certain distance apart
\n" );
document.write( "When you divided 780 by 6, you got the combined speeds of the 2 cars
\n" );
document.write( "Let the slower car's speed be S
\n" );
document.write( "Then faster car's speed = S + 20
\n" );
document.write( "We then get: S + S + 20 = 130
\n" );
document.write( "2S = 110
\n" );
document.write( "S, or speed of slower car = , or 
\n" );
document.write( "Speed of faster car = 55 + 20, or  \n" );
document.write( "

\n" );
