(8h13min4h29min×7+2h6min)÷5

Answer

To solve this expression, you need to follow the order of operations (also known as PEMDAS). The acronym stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, let's simplify the expression inside the parentheses: 8h 13min 4h 29min = 8h + 4h + 13min + 29min = 12h + 42min

Next, multiply the result by 7: (12h + 42min) × 7 = 84h + 294min

Now, let's add 2h 6min to the previous result: 84h + 294min + 2h 6min = 86h + 300min

Finally, divide the sum by 5: (86h + 300min) ÷ 5 = 17h + 60min

Therefore, the final answer is 17 hours and 60 minutes. However, 60 minutes is equal to 1 hour, so 17 hours and 60 minutes can be simplified to 18 hours.

Thus, the simplified expression is 18 hours.
