I dont understand the question what i need to do with it

Set the return value of the "check_speed" method to the string "safe" depending on the following condition: The speed passed in as an argument is at least 40. The speed passed in as an argument is less than or equal to 50. You should use the "&&" logical operator to accomplish this task.

def check_speed(car_speed)

end

For the challenge after that, you need to check if command == 'y' and all the other ones there. If it's equal to 'y' or 'yes' or 'Y' or 'YES', return "true".

Alright, so the challenge asks you to make the function "check_speed" return the string "safe" if:

  • car_speed is at least equal to 40. So it needs to be more than or equal to 40.

  • and

  • car_speed is less than or equal to 50.

Here's the code you'll need, minus the operators:

def check_speed(car_speed)
    if car_speed [operator] 40 [operator] car_speed [operator] 50
        return "safe"
    end
end

Does that help you?

Hey Bryan, that was very helpful, thank you. If you don't mind imparting just a bit more wisdom...why do we need two 'end's? Am I right in thinking it's one end for the 'if' statement and another for the 'def'?

the def needs an end and also the "if" needs an end. you created an "if" under the whole section of "def". need to end them both respectively.

I used this and it passed on the quiz, but it returns nothing on workspaces:

def check_speed(car_speed)
  if (car_speed > 39) && (car_speed <= 50)
    return "safe"
 end
end
