1. **State the problem:** Ada works Monday to Friday with working hours from 0800 to 1230 and 1330 to 1700 each day. We need to find the total number of hours she works in 5 days. 2. **Calculate daily working hours:** - Morning shift: from 0800 to 1230 is 4 hours and 30 minutes. - Afternoon shift: from 1330 to 1700 is 3 hours and 30 minutes. 3. **Convert minutes to hours:** - 30 minutes = $\frac{30}{60} = 0.5$ hours. 4. **Sum daily hours:** $$4 + 0.5 + 3 + 0.5 = 8 \text{ hours per day}$$ 5. **Calculate total hours for 5 days:** $$5 \times 8 = 40 \text{ hours}$$ **Final answer:** Ada works 40 hours in 5 days.
