Ruby Ruby Operators and Control Structures Logical Operators The And (&&) Operator

How do I complete this challenge?

The method checks he speed of a car and returns a string value: eitherr "safe" or "unsafe" Return "safe" if: The car_speed is passed as an argument is greater than or equal to the number 40. The car_speed is passed as an argument is less than or equal to the number 50. Otherwise, return "unsafe". Hint: You should use the && logical operator to accomplish this task

ruby.rb 
def check_speed(car_speed)


if (car_speed >= 40) && (car_speed <= 50)    
  return safe
elsif
  return unsafe
end

There's a couple issues. Most importantly you are missing an "end" for your check_speed method. Second, when you just say "unsafe" or "safe" without double quotes, Ruby looks for a variable called "safe" or "unsafe", and since there's no variable called "safe" or "unsafe", Ruby will return an error. Try putting double quotes around the "safe" and "unsafe" words to make them strings! :)

def check_speed(car_speed)
    if (car_speed >= 40) && (car_speed <= 50)    
        return "safe"
    elsif
        return "unsafe"
    end
end

Good luck and tell me if there's any more errors!

Hope this helps, Alex
