Ruby Ruby Operators and Control Structures Logical Operators The And (&&) Operator

Setting a conditional return value to a string, using &&

The objective for this code challenge is to set the return value of the method check_speed to the string "safe" when the two conditions are met (greater than 40 mph and less than or equal to 50 mph). In order to complete it we must also use the && operator. I've tried multiple permutations of the code you see below and got a variety of error messages, including "unexpected </>" and "Argument Error: 0 for 1". I'm totally unsure of what I'm doing wrong. Any help would be much appreciated. Thank you!

ruby.rb
def check_speed(car_speed)
  # write your code here
  car_speed(>40) && (<=50)
  puts "safe"
end

Hi Heather,

You could write if statement to solve this problem.

1 - The speed passed in as an argument is at least 40.

car_speed >= 40

2 - The speed passed in as an argument is less than or equal to 50.

car_speed <= 50

3 - Set the return value of the "check_speed" method to the string "safe"

return "safe" OR "safe" which will return automatically

def check_speed(car_speed)

  # write your code here
  if car_speed >= 40 && car_speed <= 50
    "safe"
  end

end

Hope that helps. ;)

Thanks Salman! I'd tried if statements before but forgot the second "end". Added it and voila!
