Calculating Elapsed Time Using a T Chart

This video tutorial teaches how to calculate elapsed time using the t-chart method. It covers three problems: determining arrival time for a drive, calculating the duration of a gymnastics class, and finding the start time of a race by working backwards. The video emphasizes breaking down time into manageable chunks for easier calculation.

Why is calculating elapsed time considered an important skill?

• It helps in planning daily activities like cooking and traveling.

• It is only useful for scientific experiments.

• It is a skill used exclusively in mathematics.

• It is not a necessary skill in everyday life.
