MCQ
Which of the following does not express a time interval?
- AA day
- BA second
- CA school period
- ✓Time of the first bell in the school
✓
Answer
Correct option: D.
Time of the first bell in the school
Time of the first bell in the school does not express a time interval because it has only a single value of time, while the other quantities like a day, a second and a school period can be divided into a number of shorter periods of time. Note: A time interval should have at least two values of time.
