How did Passepartout feel about not seeing anything of Omaha? By how much did they miss the China?

Passepartout wasn't sorry they hadn't seen the sights because they were not there for sighseeing.

They had seen nothing of Omaha; but Passepartout confessed to himself that this was not to be regretted, as they were not travelling to see the sights.

They missed the China by forty-five minutes.

The China, for Liverpool, had started three-quarters of an hour before!
