Elapsed Time Practice

How can practice with elapsed time questions improve mathematical skills?

• It helps in memorizing multiplication tables.

• It enhances problem-solving skills, critical thinking, and the ability to work with time-related concepts.

• It allows for faster calculations without understanding the concepts.

• It focuses solely on addition and subtraction without any real-world application.

How do you handle elapsed time that crosses over to the next hour?

• Subtract the start time from 60 minutes to find the remaining minutes in the hour, then add the minutes from the next hour.

• Simply add the start time and end time together without any adjustments.

• Ignore the minutes in the next hour and only consider the current hour.

• Convert the time to seconds and calculate the difference.

How do you convert minutes into hours and minutes?

• Multiply the total minutes by 60 to find the hours.

• Divide the total minutes by 60 to find the hours. The remainder is the minutes.

• Subtract 60 from the total minutes to find the hours.

• Convert minutes to seconds and then divide by 3600.

What is the duration of an event that starts at 11:30 AM and ends at 12:25 PM?

• 30 minutes

• 45 minutes

• 55 minutes

• 1 hour

What is a common mistake when calculating elapsed time?

• Forgetting to account for the transition between AM and PM or not properly adding minutes across the hour.

• Rounding up the total time to the nearest hour.

• Ignoring the seconds when calculating total time.

• Assuming all hours have the same number of minutes.

How do you calculate elapsed time when given a start and end time?

• To calculate elapsed time, subtract the start time from the end time. If the times are on different hours, account for the hour difference.

• To calculate elapsed time, add the start time to the end time.

• To calculate elapsed time, multiply the start time by the end time.

• To calculate elapsed time, divide the end time by the start time.

What is the duration of a lunch period that starts at 12:45 PM and ends at 1:15 PM?

• 20 minutes

• 25 minutes

• 30 minutes

• 35 minutes

What tools can help in calculating elapsed time?

• Clocks

• Rulers

• Online calculators

• Scales

If an event starts at 2:15 PM and ends at 3:18 PM, how do you find the duration?

• Break it down: from 2:15 to 3:00 is 45 minutes, and from 3:00 to 3:18 is 18 minutes. Add them together for a total of 63 minutes.

• Calculate the difference in hours and minutes separately, then convert to minutes.

• Subtract the start time from the end time directly without breaking it down.

• Use a stopwatch to measure the duration of the event.

What is elapsed time?

• The total duration of a day.

• The amount of time that passes from the start of an event to the end of that event.

• The time taken to complete a task.

• The time remaining until an event starts.
