Where did I go wrong? Having trouble understanding methods, arguments, and return. Ruby Operators and Control Structures

Question

I am having trouble understanding methods, arguments and when to use return. I've pasted the prompt below. How did I mess up my code?

The method below checks the speed of a car and returns a string value: either "safe" or "unsafe". Return "safe" if: The car_speed passed in as an argument is greater than or equal to the number 40. The car_speed passed in as an argument is less than or equal to the number 50. Otherwise, return "unsafe". Hint: You should use the && logical operator to accomplish this task. :)

ruby.rb

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

Hey Jon,

You've pretty much got it. There are just a couple things:

Because you are checking a condition that can only return 2 values, you cannot use elsif. That's used when checking multiple (more than 2) potential returns. When there is only the 2 possibilities (here it's True or False), you have to use else.
You didn't close the if statement. (Missing an end)

Just fix those up and you're good to go.

Keep Coding! :)
