Herbert takes the underground train to work and uses an escalator at the railway station. If Herbert runs up 6 steps of the escalator, then it takes him 67.5 seconds to reach the top of the escalator. If he runs up 14 steps of the escalator, then it takes him only 47.5 seconds to reach the top.

How many seconds would it take Herbert to reach the top if he did not run up any steps of the escalator at all?
