Calculating Elapsed Time Concepts

This video tutorial explains how to calculate elapsed time using a timeline method. It begins with a simple example of finding the elapsed time between 6:30 and 9:00, demonstrating how to use jumps on a timeline to reach the next full hour and then to the end time. The video then covers a more complex example involving crossing a 12:00 hour, showing how to handle such cases. The tutorial concludes with a request for feedback and subscription.

What is the main topic of the video?

• Division

• Multiplication

• Elapsed time

• Addition and subtraction

What is the first step in calculating elapsed time using a timeline?

• Jump to the next full hour

• Subtract the start time from the end time

• Add the start time to the end time

• Multiply the start time by the end time

How much time passes from 6:30 to 7:00?

• 30 minutes

• 1 hour

• 45 minutes

• 15 minutes

What is the total elapsed time from 6:30 to 9:00?

• 2 hours

• 3 hours

• 2 hours and 30 minutes

• 1 hour and 30 minutes

What should you do if the start time is not an exact hour?

• Add 15 minutes

• Multiply by 2

• Subtract 30 minutes

• Jump to the next full hour

What is the purpose of labeling times on the timeline?

• To easily add up the total elapsed time

• To divide the times

• To subtract the times

• To multiply the times

What is the elapsed time from 7:00 to 9:00?

• 1.5 hours

• 3 hours

• 1 hour

• 2 hours

Why is it more challenging to calculate elapsed time when crossing a 12:00 hour?

• Because it involves multiplication

• Because it requires division

• Because the numbers are larger

• Because students often try to subtract the times directly

What is the first jump made when calculating elapsed time from 10:57 to 1:15?

• 30 minutes to 11:27

• 15 minutes to 11:12

• 1 hour to 11:57

• 3 minutes to 11:00

How many full hours pass from 11:00 to 1:00?

• 1 hour

• 3 hours

• 1.5 hours

• 2 hours
