We have the following formula:
\n" ); document.write( "\"s=2sqrt%285L%29\"
\n" ); document.write( "where L is given as 50.
\n" ); document.write( "--
\n" ); document.write( "step 1 - replace L with 50 to get
\n" ); document.write( "\"s=2sqrt%285%2A50%29\"
\n" ); document.write( "we can find s as about
\n" ); document.write( "s ~ 31.6227 miles / hr.
