You can put this solution on YOUR website!
Average speed is total distance divided by total time.
\n" ); document.write( "If the hill was one mile distant, then it took him 1/6 hour on the way up, and 1/12 hour on the way down.
\n" ); document.write( "Speed = Total distance/Total time
\n" ); document.write( "Speed = (2 miles)/(1/6 + 1/12) = 2/(1/4) = 8 miles per hour
\n" ); document.write( "and not what you'd expect... \n" ); document.write( "

\n" );
