A bakery makes 160 muffins every 4 hours. At this rate, how many hours will it take the bakery to make 1,280 muffins?

To determine how many hours it will take the bakery to make 1,280 muffins at the rate of 160 muffins every 4 hours, we can follow these steps:

1. **Find the rate of muffins per hour:**
\[
\text{Rate} = \frac{160 \text{ muffins}}{4 \text{ hours}} = 40 \text{ muffins per hour}
\]

2. **Calculate how many hours are needed to make 1,280 muffins:**
\[
\text{Time} = \frac{1,280 \text{ muffins}}{40 \text{ muffins per hour}} = 32 \text{ hours}
\]

Thus, it will take the bakery **32 hours** to make 1,280 muffins.
