Answer 1

1) 243 с + 472 с = 715с

Answer 2

To calculate the sum of the given time durations, we need to add the minutes and seconds separately.

Given time durations: 12 minutes 23 seconds 7 minutes 52 seconds

Adding the minutes:

12 minutes + 7 minutes = 19 minutes

Adding the seconds:

23 seconds + 52 seconds = 75 seconds

Since there are 60 seconds in a minute, we need to convert the 75 seconds to minutes and seconds.

Dividing 75 seconds by 60, we get: 75 seconds ÷ 60 = 1 minute remainder 15 seconds

So, the total duration is 19 minutes 1 second (19m 1s).

Therefore, the sum of the given time durations 12 minutes 23 seconds and 7 minutes 52 seconds is 19 minutes 1 second.
