1. **Problem:** Dana reads at a rate of 2 pages every 3 minutes. The fourth chapter has 28 pages. How many minutes will it take Dana to read the chapter? 2. **Formula:** Time = \frac{Total\ pages}{Pages\ per\ minute} 3. **Calculate pages per minute:** $$\text{Pages per minute} = \frac{2}{3}$$ 4. **Calculate time:** $$\text{Time} = \frac{28}{\frac{2}{3}} = 28 \times \frac{3}{2}$$ 5. **Simplify:** $$28 \times \frac{3}{2} = \frac{28 \times 3}{2} = \frac{84}{2} = 42$$ 6. **Answer:** It will take Dana 42 minutes to read the fourth chapter. --- Since the user asked multiple questions, but per instructions, only the first is solved here.
