Question

12 мин 30 с - 4 мин 50 с + 9 мин 45с

Answer 1

12 мин 30 с - 4 мин 50 с + 9 мин 45с = 17min 15s

1h=60min
11 min 90s - 4 min 50s = 7 min 40s
7 min 30s + 9 min 45s = 16 min 85s
1min = 60s
16min 85s = 17 min 25s

Answer 2

750с-290с+585с=1045секунд

Answer 3

To calculate the total time, we need to add up all the given times:

12 minutes 30 seconds

• 4 minutes 50 seconds

• 9 minutes 45 seconds

First, let's convert all the times to seconds to make the addition easier:

12 minutes 30 seconds = (12 x 60) + 30 = 750 seconds 4 minutes 50 seconds = (4 x 60) + 50 = 290 seconds 9 minutes 45 seconds = (9 x 60) + 45 = 585 seconds

Now we can add them up:

750 - 290 + 585 = 1045 seconds

Finally, let's convert the result back to minutes and seconds:

1045 seconds = 17 minutes 25 seconds

Therefore, the total time is 17 minutes 25 seconds.
