I don't understand why my code isn't passing...thanks in advance for the help :)

def check_speed(car_speed) 
check_speed = gets.chomp.to_i  

  if (check_speed >= 40) && (check_speed <= 50) 
     puts "safe" 
end

1) remove the whole line that does gets.chomp - they are not asking for it

2) do comparisons on car_speed, not check_speed (parentheses are not needed)

3) add another end after the if statement

4) remove puts - they are asking you to return that string, not print it, so you can just write "safe" on this line

You need to have the whole 'if' statement in parenthesis. Like this: if ((check_speed >= 40) && (check_speed <= 50))

I believe you need two ends. One for the function and one for the if statement.
