Calculating Time Differences

The video tutorial explains how to calculate the time difference between 4:58 PM and 1:15 AM. It uses a visual aid by drawing clocks to represent the times and applies the 12 o'clock rule to perform the calculation. The process involves borrowing minutes to subtract and then adding the remaining time to find the total hours and minutes passed. The final result is 8 hours and 17 minutes.

What is the initial time given in the problem?

• 6:00 PM

• 12:00 PM

• 1:15 AM

• 4:58 PM

What is the final time given in the problem?

• 4:58 PM

• 6:00 PM

• 1:15 AM

• 12:00 PM

Why is a pictorial aid like a clock useful in this problem?

• It helps visualize the time difference.

• It makes the problem more complex.

• It is required for all time calculations.

• It is a traditional method.

What is the purpose of the 12 o'clock rule?

• To calculate time differences across AM and PM.

• To convert time to a 24-hour format.

• To avoid using clocks.

• To simplify addition.

What is the first step in the 12 o'clock rule?

• Use a calculator.

• Convert AM time to PM.

• Subtract the PM time from 12 o'clock.

• Add 12 hours to the PM time.

Why do we need to borrow time in this calculation?

• To simplify the problem.

• To convert time to a 24-hour format.

• To avoid using a calculator.

• To make subtraction possible.

What do we borrow when we cannot subtract minutes directly?

• A month or 30 days.

• A week or 7 days.

• A day or 24 hours.

• An hour or 60 minutes.

What is the result of 60 minus 58 in the calculation?

• 12

• 32

• 22

• 2

What is the result of 11 minus 4 in the calculation?

• 8

• 5

• 7

• 6

What is the next step after borrowing time?

• Add the AM time to the result.

• Subtract the AM time from the result.

• Convert the result to a 24-hour format.

• Use a calculator to verify.
