travel "long distances" or "a long distance"

[sunsunmoon]

Traveling long distances by car can be extremely boring, at least for the passengers.

Would it be okay to say a long distance instead? Can it also be boring to travel one long distance?
(I know what singular and plural are, of course.)

Yes.

Is "long distances" preferable in the context? If it is, could you explain why?

Come, come, sunsunmoon. You said in your first post that you knew about singular and plural.

5JJ,

I knew about singular and plural, but I wasn't quite sure why you preferred one to the other in that context. I'm wondering if I shouldn't have said, "I know what singular and plural are," then. I apologize for not making myself understood well.
