Elapsed Time Problem Solving

The video tutorial covers the concept of elapsed time in math, explaining how to calculate it using a number line. It provides examples of determining elapsed time, end time, and start time through practical scenarios like a beach trip and a party. The tutorial emphasizes the usefulness of a number line for visualizing time progression and solving problems without a clock.

What is elapsed time?

• The time shown on a clock

• The total time spent on a task

• The difference between start and end times

• The time it takes to complete a task

Which of the following is NOT a component of elapsed time problems?

• Distance traveled

• Elapsed time

• End time

• Start time

Why is a number line useful for solving elapsed time problems?

• It is faster than using a clock

• It helps visualize time progression

• It is the only method available

• It is more accurate than a calculator

What is the first step in using a number line to solve elapsed time problems?

• Draw circles for hours

• Calculate the end time

• Estimate the total time

• Write down the start time

In the example problem, what is the start time for the beach trip?

• 5:20 PM

• 4:20 PM

• 8:50 PM

• 3:20 PM

How many hours were spent at the beach in the example problem?

• 7 hours

• 6 hours

• 5 hours

• 4 hours

What is the total elapsed time for the beach trip?

• 6 hours and 30 minutes

• 4 hours and 30 minutes

• 5 hours and 30 minutes

• 7 hours and 30 minutes

In the second example, what is the known start time?

• 1:15 PM

• 4:15 PM

• 2:15 PM

• 3:15 PM

How long is the elapsed time in the second example problem?

• 6 hours and 55 minutes

• 5 hours and 55 minutes

• 4 hours and 55 minutes

• 3 hours and 55 minutes

What is the end time in the second example problem?

• 6:10 PM

• 8:10 PM

• 5:15 PM

• 7:10 PM
