Trouble with this challenge in Ruby

I cant seem to get this challenge correct, can someone help me. I know how to make the if statement if(car_speed >= 40) && (car_speed <=50) but the rest I just cant get

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

  • missed the end for if condition
  • also, you can return "safe" directly without assign it to a variable first.
def check_speed(car_speed)
  # write your code here
  if(car_speed >= 40) && (car_speed <= 50)
    "safe"
  end
end

This is how it should look like:

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

end

After You declare conditional structure like "IF", You need to always close it with "end". This is very important and You should keep an eye for it. Also You do not need to declare a new variable, Your task is to just return a string "safe".

Also please note that You do not need to specify "return" keyword in Ruby because the last line of any method is returned by default, i used it to make it more clear.
