Question

13 h 5 min -3*(2 h 48 min:6+3 h 47 min)=

Answer 1

To solve this expression, let's break it down step by step:

1. Convert all times to minutes:

   • 13 hours and 5 minutes = (13 * 60) + 5 = 785 minutes
   • 2 hours and 48 minutes = (2 * 60) + 48 = 168 minutes
   • 3 hours and 47 minutes = (3 * 60) + 47 = 227 minutes

2. Calculate the expression inside the parentheses:

   • 2 hours 48 minutes : 6 = (168 + 48) / 6 = 216 / 6 = 36 minutes

3. Substitute the calculated values back into the original expression:

   • 785 - 3 * (36 + 227)

4. Perform the operations within the parentheses:

   • 36 + 227 = 263

5. Multiply 3 by 263:

   • 3 * 263 = 789

6. Subtract the result from 785:

   • 785 - 789 = -4

So, the final result is -4.
