Summary:
This video teaches how to calculate time intervals between a start time and an end time. It explains a step-by-step method:
Subtract the start time from the end time.
Subtract the hours.
Compare the minutes:
If the start minutes are less than or equal to the end minutes, subtract normally.
If the start minutes are greater, subtract 1 from the hour total, add 60 minutes to the end minutes, then subtract the start minutes.
Several examples are worked through, including:
Time intervals within the same a.m. or p.m. period.
A more challenging bonus example involving a time span from a.m. to p.m., which requires converting the p.m. time to 24-hour format by adding 12 to the hour.
Key takeaway: Always break time interval problems into manageable steps, and adjust for minute and a.m./p.m. differences when needed.
