Answer 3

Let's calculate the given expressions step by step:

4 hours 40 minutes + 20 minutes: To add the hours and minutes, we need to convert everything to the same unit. Since there are 60 minutes in an hour, we can convert the hours to minutes. Then we can add the minutes together.

4 hours 40 minutes = (4 * 60) + 40 = 240 + 40 = 280 minutes

Now we can add the 280 minutes and 20 minutes together:

280 minutes + 20 minutes = 300 minutes

Therefore, 4 hours 40 minutes + 20 minutes equals 5 hours 300 minutes.

Next, let's calculate:

5 hours 34 minutes - 36 minutes: Similarly, we need to convert everything to the same unit before subtracting.

5 hours 34 minutes = (5 * 60) + 34 = 300 + 34 = 334 minutes

Now we can subtract 36 minutes from 334 minutes:

334 minutes - 36 minutes = 298 minutes

Therefore, 5 hours 34 minutes - 36 minutes equals 4 hours 298 minutes.

Note: Since there are 60 minutes in an hour, if the number of minutes exceeds 60, it rolls over to the hour value.
