You can put this solution on YOUR website!
First set up the equation:
\n" ); document.write( "Speed=distance/time so time =distance/speed
\n" ); document.write( "Let x represent the time:
\n" ); document.write( "\"6%2F10%2B3%2F5=x\"
\n" ); document.write( "so:\"10%286%2F10%29%2B10%283%2F5%29=10%28x%29\"
\n" ); document.write( "6+6=10x
\n" ); document.write( "x=1.2
\n" ); document.write( "Hence, the total time was 1.2hours.
