Ruby Operators and Control Structures

I need help figuring out what is wrong with my code:

 def check_speed(car_speed)

  speed = car_speed.to_i

  if (speed > 40)  && (speed <= 50)

    puts "safe"

  end

end

The message that I'm getting is that the check_speed method is not giving the correct output.

why did you add "speed = car_speed.to_i" ?

Hi Patrick,

  • Need to add equal (=) that would be maximum up to 40. Also other way, you can do this speed > 39 instead 40.
  • return value for "safe" string according to the question, puts vs return are not the same thing.
 def check_speed(car_speed)

  speed = car_speed.to_i

  if (speed >= 40)  && (speed <= 50)

    return "safe"

  end

end

Hope that helps. ;)

Hi Bogere,

The to_i method is added to convert the car_speed argument from an input string to an actual number.

Hope that helps.
