I can't see what's wrong with my answer, any help?

benchmarker.run("method", { 100.times { puts "Hello" } })

class SimpleBenchmarker
  def run(description, &block)
    start_time = Time.now
    end_time = Time.now
    elapsed = end_time - start_time

    puts "\n#{description} results"
    puts "Elapsed time: #{elapsed} seconds"

benchmarker = SimpleBenchmarker.new
benchmarker.run("method", { 100.times { puts "Hello" } })
