He had the place to himself for a quarter of an hour at the most.

I've only been here about quarter of an hour myself.

For a quarter of an hour I sat and thought.

One came into view after another quarter of an hour.

They'll be here in less than a quarter of an hour, I should think.

A quarter of an hour later they were on their way.

Then I am a quarter of an hour late already.
