EX. "Whether you stay in your room or sit in the garden is not my concern!"

"About" This means close to or roughly. Meaning the time you arrive by car or train is close together. There might only be a five-minute difference in arrival times.

When trying to convey that something may take about the same amount of time to do something it's useful to use adverbs.Adverbs modify the meaning of adjectives and verbs, expressing manner, place and time.In the context of these statements, the adverbs suggest the amount of time the journey might take but suggests that it is almost so but not completely accurate.
