You have two problems going on within your code:

1)You want to make sure car_speed is greater than OR equal to 40 and car_speed is less than OR equal to 50

def check_speed(car_speed)
  # write your code here
  if (car_speed >= 40) && (car_speed <= 50)
    return "safe"

  else
    return "unsafe"

end

2)Your if statement is missing the end clause.

def check_speed(car_speed)
  # write your code here
  if (car_speed >= 40) && (car_speed <= 50)
    return "safe"
  else
    return "unsafe"
  end
end

When you say that you tried to run it on a work file, could you elaborate a little more as to where you were running the code as well as what was expected vs what actually happened? Thanks.
