Update the check_speed method to compare the value in the car_speed parameter to the value in the speed_limit parameter.

Update the check_speed method to compare the value in the car_speed parameter to the value in the speed_limit parameter. If car_speed is greater than speed_limit, print the message "Slow down!" Otherwise, print the message "Safe travels!"

ruby.rb 
def check_speed(car_speed, speed_limit)
  if(car_speed > speed_limit)
    print "Slow down!" 
  else
    print "Safe travels!"
end
check_speed(20, 40)

Hey There,

If you look at the error message you get when you try and check your work, it gives away what's wrong.

syntax error, unexpected end-of-input, expecting keyword_end

So, your method and conditional is correct, except you forgot the end keyword to end the if statement. Add that in and you're good to go.

Keep coding! :dizzy:

Hi. It took me a while too. Because in the previous videos training, we didn't need to end the if statement before starting the else statement. e.g:

print "Enter name: " name = gets.chomp

if name == "Jason" puts "That's my name, too!" else puts "Hi #{name}!" end
