Question

13h 5 min- 3• (2h 48min:6+3h 47min)=

Answer 1

Ответ:

928 min or 15 h 46 min

Пошаговое объяснение:

(13*60+5)-(3( (2*60)+48)/6) + (3*60+47)) = 928

Answer 2

Let's break down the calculation step by step:

1. Start with the first part of the equation: 13 hours 5 minutes.

2. Now, let's deal with the expression inside the parentheses: 2 hours 48 minutes divided by 6 plus 3 hours 47 minutes.

   First, calculate 2 hours 48 minutes divided by 6: (2 hours 48 minutes) / 6 = (2 * 60 minutes + 48 minutes) / 6 = (168 minutes) / 6 = 28 minutes.

   Now, add the result to 3 hours 47 minutes: 3 hours 47 minutes + 28 minutes = 3 hours 75 minutes.

3. Finally, subtract the result from step 2 from the original value in step 1: 13 hours 5 minutes - 3 hours 75 minutes.

Now, subtract the minutes and hours separately:

Minutes: 5 minutes - 75 minutes = -70 minutes.

Hours: 13 hours - 3 hours = 10 hours.

So, the final result is 10 hours and -70 minutes. However, negative minutes are not a standard representation. To convert this into a more standard format, you can borrow an hour from the hours part:

10 hours - 1 hour = 9 hours 60 minutes - 70 minutes = -10 minutes

So, the final result is 9 hours - 10 minutes.
