1. **State the problem:** Ron traveled 6.8 miles in 1.2 hours. We need to find the time it will take to travel 20 miles at the same rate. 2. **Formula used:** Time = Distance \div Rate 3. **Calculate the rate:** Rate = Distance \div Time = $\frac{6.8}{1.2}$ miles per hour. 4. **Simplify the rate:** $$\frac{6.8}{1.2} = \frac{\cancel{6.8}}{\cancel{1.2}} = 5.6667 \text{ miles per hour (approx)}$$ 5. **Calculate the time for 20 miles:** $$\text{Time} = \frac{20}{5.6667}$$ 6. **Simplify the time:** $$\frac{20}{5.6667} \approx 3.53 \text{ hours}$$ 7. **Interpretation:** The closest answer to 3.53 hours is 3.5 hours. **Final answer:** 3.5 hours
