Kristina and Darrin are running around a circular track with the same angular speed. Darrin is running on the inside lane which has radius $40$ ft and Kristina is running on the outside lane which has radius $44$ ft. If Kristina is running at a rate of $11$ ft per second, how fast is Darrin running?

For every $11$ ft Kristina runs, how many feet does Darrin run?
