Having trouble getting past Challenge Task 1 (use of &&)

OK, I'm having trouble getting past this first challenge. I am checking that the speed is indeed >= 40 AND is <= 50. I have tried several different ways and I can't get past this one. Code is posted below. Any suggestions??

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

Set the return value of the "check_speed" method to the string "safe" depending on the following condition:

Some issues with your code

  • missing a closing end for if conditional
  • no return value
  • check_speed is function name, you shouldn't use it on the function body here, use the car_speed argument instead.
def check_speed(car_speed)
  # write your code here
  if (car_speed >= 40) && (car_speed <= 50)
    return "safe"
  end
end

and the use of return keyword is optional here, but keeping the return keyword probably helps people see more clearly that "safe" is indeed the return value here.

You're close, here's the correct answer:

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

You were using the method name where it should have been the method's argument car_speed. You also need to return a value and end your if statement.

Ouch, I wasn't even close. I think that things are starting to get more challenging and that a person really has to 'think' more. I did indeed try the car_speed right off the bat immediately after the first FAIL and saw that immediately during my six or so attempts before posting to the forum. The return statement, however, completely threw me off (sigh). I believe the problem is that I'm not reading the statement/question in the quiz correctly (my fault); I am sometimes having problems interpreting what they are asking. Not sure how I'm going to resolve this going forward as I do tend to think daily in a different way than someone presents something to me (orally or written). This has always been a problem for me and I have never learned how to resolve it. Suggestions are welcome (if you have any!). Thanks so much.
