Elapsed Time: Identifying Start, Change, and End Times in Real World Situations

This video tutorial teaches about elapsed time by identifying start, change, and end times in real-world scenarios. It uses examples like Tanya's morning routine and baking a cake to illustrate how to solve elapsed-time word problems. The lesson emphasizes understanding the problem, identifying key information, and visualizing the scenario to find solutions.

What is the first step in solving an elapsed time problem?

• Identify the end time

• Calculate the total time

• Estimate the duration

• Identify the start time

In the example with Tanya, what is the end time?

• 6:00 AM

• 7:00 AM

• 8:00 AM

• 9:00 AM

How long does Tanya take to get ready if she wakes up at 6:00 AM and leaves at 7:00 AM?

• 1 hour and 15 minutes

• 1 hour

• 45 minutes

• 30 minutes

If a cake is put in the oven at 4:00 PM and needs to bake for 45 minutes, when should it be taken out?

• 5:15 PM

• 4:30 PM

• 4:45 PM

• 5:00 PM

What is the 'change' in an elapsed time problem?

• The total time of the day

• The end time

• The start time

• The duration between start and end
