# Up an Escalator

JimmyÂ takes the underground train to work and uses an escalator at the railway station. If Jimmy runs up 7 steps of the escalator, then it takes him 28.5 seconds to reach the top of the escalator. If he runs up 13 steps of the escalator, then it takes him only 19.5 seconds to reach the top.

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