Ruby Booleans Help! First if statement

I need some assistance putting up the framework for this challenge. I can fill in the blanks after that.

Thank you

boolean.rb 
car_speed = 50
speed_limit = 45

Hi Avery,

There are a couple of ways you can write this syntax. One would be all on one line, something like: 

method_name if condition_met

The condition_met could be a comparison such as something being greater than something else. Take the two variables in this challenge - car_speed and speed_limit. You could compare those with a binary operator, perhaps?

Alternatively, you can structure this over more than one line. Something like:

if condition_met
  do_this
end

Let me know if you need more - those are just a couple of hints.

Steve.

Thanks! this did the trick. I ended up misplacing the else statement.

I think you need to use a multi-line if statement if you want an else clause. 

flash_car_speed if car_speed > speed_limit

... works fine for the single test. I don't think you can bung an else on the end of that so you'd need something like:

if car_speed > speed_limit
  flash_car_speed
else
  display_car_speed
end

Shame, 'cos I like the single line syntax better.
