Recently, while in London, I decided to walk down the escalator of a tube station. I did some quick calculation in my mind. I found that if I walk down twenty-six steps, I require thirty seconds to reach the bottom. However, if I am able to step down thirty-four stairs I would only require eighteen seconds to get to the bottom. If the time is measured from the moment the top step begins to descend to the time I step off the last step at the bottom.
Can you tell the height of the stairway in steps?

A man I know, who lives in my neighbourhood, travels to Chinsura everyday for his work. His wife drives him over to Howrah Station every morning and in the evening exactly at 6 p.m.She picks him up from the station and takes him home.
One day he was let off at work an hour earlier, and so he arrived at the Howrah Station at 5 p.m. instead of at 6 p.m. He started walking home. However,he met his wife enroute to the station and got into the car: They drove home arriving 10 minutes earlier than usual.
How long did the man walk, before he was picked up by his wife?
