To solve this expression, first convert all the hours and minutes into minutes.

8 hours and 13 minutes is equal to 8 × 60 + 13 = 493 minutes.

4 hours and 29 minutes is equal to 4 × 60 + 29 = 269 minutes.

2 hours and 6 minutes is equal to 2 × 60 + 6 = 126 minutes.

Now, substitute the values back into the expression:

((493 + 269) × 7 + 126) ÷ 5

To simplify:

(762 × 7 + 126) ÷ 5

Multiply first:

(5334 + 126) ÷ 5

Add:

5460 ÷ 5

Divide:

1092

So, the final answer is 1092 minutes.
