Estimate a safe speed x for a car for a stopping distance of 522 feet. Use the formula below
\n" ); document.write( "1/9^2 + 11/3x = 522
\n" ); document.write( "A safe speed would be how many feet?
\n" ); document.write( "-------------
\n" ); document.write( "1/81 + 11x/3 = 522
\n" ); document.write( "11x/3 = 42281/81
\n" ); document.write( "11x = 42281/27
\n" ); document.write( "x = 42281/297
\n" ); document.write( "x =~ 142.36
\n" ); document.write( "I don't know the units, but it's not feet.
\n" ); document.write( "
\n" );
