I do not understand when I get the error, Your code isn't returning the right output?

I already tried using return instead of puts.

ruby.rb 
car_speed = 45

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

Hey Alec,

First off, delete the car_speed = 45 line. The challenges don't like it when you add something it didn't ask for. Many times this will cause you to not be able to pass the challenge.

As to your code, everything is correct, except you did add another thing the challenge didn't want. The challenge just wants you to "Return" the value "safe," but you are trying to print it to the screen. Just use an implicit return at the end of the conditional.

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

Hope that helps you. Keep Coding! :)
