Issue with && operator.

So I'm having a fair amount of difficulty with this task, I've tried a lot of different options and trawled through the questions, trying out other peoples different methods to no avail! If I could get some advice that'd be appreciated!

ruby.rb
def check_speed(car_speed)

  speed = car_speed.to.i

  if (speed >= 40) && (speed <= 50)
    return "safe"
  elsif
    return "unsafe"
end

end

Hiya Andrew! There are a couple of issues with your code.

  • You dont have to assign "car_speed" to another variable or convert it to an "integer" coz you're kinda getting derailed from the challenge. I'd highly recommend you to stick to the challenge, keep it simple and concise. So yeah remove that part of statement , and restore back "speed" with "car_speed".

  • Replace "elsif" with "else". The "elsif" conditional takes a boolean expression and if wont pass a boolean expression, Ruby will throw a syntax error.

Here is my code for reference or if you get stuck again:

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