PUTTING IT INTO PRACTICE
Speaking Time: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Script words (integer) | 600 |
| Speaking rate (words/minute) | 120 |
| Result | 5 minutes |
- Check the input labels and enter the example values above.
- Apply the relationship: Speaking time = words/words per minute.
- The result is 5 minutes, rounded for display.
How to interpret your result
Pauses, demonstrations and audience interaction add time beyond continuous speech.
Decimal hours and clock notation are different: 1.5 hours is 1 hour 30 minutes. Clock-only tools cannot infer dates or daylight-saving transitions. Estimates based on a constant reading or speaking rate exclude breaks.
Frequently asked questions
Does 1.30 decimal hours mean one hour thirty minutes?
