Please tell me whether the following two sentences are correct or acceptable to native speakers of English. Thanks a lot.
A. He never thought that he had any obligation to do so.
That's fine provided it fits whatever the context might be.
B. He spent (or took) ten minutes to get to the train station.
It's not exactly wrong but it sounds unnatural to my ears.
It took him ten minutes to get to the train station.
He took ten minutes getting to the train station. He spent ten minutes getting to the train station.
