I'm not sure where I'm going wrong in this question..

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

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

Hey Sameet,

you have a few small mistakes in your code. Firstly you forgot to close your if block. The other problem is that the challenge doesn't want you to return "unsafe" in an elsif block so you should just return it in an else block. Also note that your elsif block would never be executed because there is no number that's less than or equal 40 and greater than or equal 50, if you would want to use the elsif block you should use the or (||) operator.

If you write it like this it should work

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

I hope that helps, if you don't understand something or have further questions feel free to ask, good luck! :)
