Bill Drives to work. Because of traffic conditions, he averages 30 miles per hour. He returns home averaging 40 miles per hour. The total time is four and a half hours. Write and solve an equation to find the time Bill spends driving to work.

It's totally unnecessary to find distance, especially since you're looking for, and can determine time without doing so
\n" );
document.write( "Let time spent driving to work, be T
\n" );
document.write( "Then time spent driving home = , or 
\n" );
document.write( "We then get the following distance equation: 
\n" );
document.write( "30T = 180 – 40T
\n" );
document.write( "30T + 40T = 180
\n" );
document.write( "70T = 180
\n" );
document.write( "T, or time spent driving to work = , or  hours \n" );
document.write( "

\n" );
