1. The problem states that item C has a transport quantity of 880 tonnes per 40-hour week. 2. First, find the transport rate per hour for item C by dividing 880 tonnes by 40 hours: $$\text{Rate per hour} = \frac{880}{40} = 22$$ tonnes per hour. 3. Next, calculate the total hours in two 8-hour days: $$2 \times 8 = 16$$ hours. 4. Multiply the hourly rate by 16 hours to find the total tonnes transported in two 8-hour days: $$22 \times 16 = 352$$ tonnes. 5. Therefore, the number of tonnes of item C transported in two 8-hour days is 352 tonnes.
