Answer 3

To solve the given examples, we'll perform the calculations step by step.

Example 1: Adding Time

We need to add the following times: - 4 hours 53 minutes - 1 hour 45 minutes - 1 hour 21 minutes 48 seconds

To add these times, we add each component separately and carry over any excess minutes or seconds.

Step 1: Add the hours: 4 hours + 1 hour + 1 hour = 6 hours

Step 2: Add the minutes: 53 minutes + 45 minutes + 21 minutes = 119 minutes

Step 3: Add the seconds: 48 seconds

Since we have 119 minutes, which is more than 60 minutes, we can convert the excess minutes into hours.

Step 4: Convert the excess minutes into hours: 119 minutes ÷ 60 minutes/hour = 1 hour 59 minutes

Now we have 6 hours, 1 hour 59 minutes, and 48 seconds.

Final Answer: The total sum of the given times is 6 hours 1 minute 48 seconds.

Example 2: Subtracting Time

We need to subtract the following times: - 43 days - 1 day 8 hours 57 minutes - 9 hours 36 minutes

To subtract these times, we'll perform the calculations step by step.

Step 1: Convert the days into hours: 43 days × 24 hours/day = 1032 hours

Step 2: Subtract the hours: 1032 hours - 1 hour 8 hours = 1023 hours

Step 3: Subtract the minutes: 1023 hours - 57 minutes - 36 minutes = 930 hours

Final Answer: The result of subtracting the given times is 930 hours.

Example 3: Multiplying Time

We need to multiply the following times: - 5 hours - 43 minutes

To multiply these times, we'll convert them into minutes and then perform the multiplication.

Step 1: Convert the hours into minutes: 5 hours × 60 minutes/hour = 300 minutes

Step 2: Multiply the minutes: 300 minutes × 43 minutes = 12,900 minutes

Final Answer: The result of multiplying the given times is 12,900 minutes.
