during a recent trip jackie travelled 62km. part of it was on a congested highway. the total trip took 2 hours, of which 1.25h were spent in congestion. Find her speed in the congested highway if she travelled 40 km/h faster on the highway that was not congested
\n" ); document.write( "

With S being the average speed on congested highway, we get the following DISTANCE equation: 1.25S + .75(S + 40) = 62
\n" );
document.write( "1.25S + .75S + 30 = 62
\n" );
document.write( "2S = 32
\n" );
document.write( "S, or speed on congested highway is: 
\n" );
document.write( "That's all! Nothing COMPLEX and/or CONFUSING!
\n" );
document.write( "Never, ever make problems like these more COMPLEX than they are by converting the given decimals to fractions, like the other person did.
\n" );
document.write( "Most people do not like to work with fractions so I'd advise you to stay away from them. 
\n" );
document.write( "If you wish to convert the decimals, my advice would be to convert to WHOLE NUMBERS/INTEGERS, although this problem doesn't need any 
\n" );
document.write( "conversions because as is obvious, 1.25S + .75S totals 2S. This is RIDICULOUS!! \n" );
document.write( "

\n" );
