How to make a Ruby method return a certain string based on its argument meeting certain criteria

I'm confused. The lesson before this code challenge showed how to use && and || inside If statements. I get that.

But the code challenge suddenly requires the use of this kind of statement inside a method, which I have a much looser grasp of than if statements.

Any help on this problem appreciated.

ruby.rb 
def check_speed(car_speed)
  (car_speed > 40) && (car_speed <= 50)
  puts "safe"
end

The exercise wants you to "return value", not print (puts) it on the screen. Also, "at least 40" means that it can also be equal to 40, and the whole thing should be a part of the if statement - look at minute 2:30 in the video to see how this if statement should be constructed. Make some experiments and get back to me here if you still have problems.

Hi Maciej,

Thank you so much for your response! By fooling around with the method a good bit more I finally achieved an acceptable response.

I have to say I had no idea an if statement could go inside a method. This was never demonstrated in any of the videos up to this point, nor did I notice an example of that in any of my Google searches about Ruby methods while trying to figure this one out.

But now I know. I appreciate you pointing me in the right direction!
