Question

(3ч 26 мин 4 сек -1 я 48мин 20 сек)*4​

Answer 1

Таак.

1 час = 60 минут

1 минута = 60 секунд

((3*60*60)ч + (26*60)мин + 4 сек - (1*60*60)ч + (48*60)мин + 20 сек) * 4 =

(12364-3608)*4= 8756*4 = 35024 сек

35024/3600 = 9ч и остаток 2624 сек

2625/60 = 43мин и остаток 45 сек

Итог 9ч 43мин 45сек  

Answer 2

To calculate the result, let's first convert all the given durations to seconds and then perform the subtraction and multiplication.

1 hour = 3600 seconds 1 minute = 60 seconds

Duration 1: 3 hours 26 minutes 4 seconds = (3 * 3600 seconds) + (26 * 60 seconds) + 4 seconds = 10800 seconds + 1560 seconds + 4 seconds = 12364 seconds

Duration 2: 1 hour 48 minutes 20 seconds = (1 * 3600 seconds) + (48 * 60 seconds) + 20 seconds = 3600 seconds + 2880 seconds + 20 seconds = 6500 seconds

Now, let's perform the subtraction:

12364 seconds - 6500 seconds = 5864 seconds

Finally, let's multiply the result by 4:

5864 seconds * 4 = 23456 seconds

Now, we need to convert the result back to hours, minutes, and seconds:

1 hour = 3600 seconds

23456 seconds = 23456 / 3600 hours (quotient) + 22456 % 3600 seconds (remainder)

23456 seconds = 6 hours (approx) + 5456 seconds

Now, we convert the remaining seconds to minutes:

1 minute = 60 seconds

5456 seconds = 5456 / 60 minutes (quotient) + 5456 % 60 seconds (remainder)

5456 seconds = 90 minutes (approx) + 16 seconds

So, the final result is approximately 6 hours 90 minutes 16 seconds. However, we need to adjust the 90 minutes to be in hours and minutes format:

90 minutes = 1 hour 30 minutes

Thus, the final result is approximately 7 hours 30 minutes 16 seconds.
