The formula R=2sqrt5L can be used to approximate the speed R in miles per hour,
\n" ); document.write( " of a car that has left skid marks of the length L in feet,
\n" ); document.write( " how far will a car skid at 20 mph.
\n" ); document.write( "The car will skid ? feet
\n" ); document.write( ":
\n" ); document.write( "\"R=2%2Asqrt%285L%29\"
\n" ); document.write( ":
\n" ); document.write( "\"2%2Asqrt%285L%29\" = 20
\n" ); document.write( ";
\n" ); document.write( "\"sqrt%285L%29\" = \"20%2F2\"
\n" ); document.write( ":
\n" ); document.write( "\"sqrt%285L%29\" = 10
\n" ); document.write( "square both sides
\n" ); document.write( "5L = 100
\n" ); document.write( "L = \"100%2F5\"
\n" ); document.write( "L = 20 feet at 20 mph
\n" ); document.write( "
\n" ); document.write( "
\n" );
