If Angela runs up 5 steps of an escalator, it takes her 40 seconds to reach the top of the escalator. If she runs up 14 steps of the escalator, then it takes her only 26 seconds to reach the top.

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