Thomas has constant speeds for both running and walking. When a down-escalator is moving, Thomas can run down it in 15seconds or

walk down it in
30seconds. One day, when the escalator was broken (and stationary), it took Thomas
20seconds to run down it.

How long, in seconds, would it take Thomas to walk down the broken escalator?
