a (unit of time) or two

For only one or a few units of time specified (minutes, hours, days, etc.). Is it all right if I borrow the car for an hour or two? I'd like to drive to the mall. You can keep the book for a day or two, but I need it back by this weekend to study for my exam. Nah, it'll only take me a minute or two to find that file because I keep everything over here alphabetized.
