1. **State the problem:** Pete walked around a park three times. We need to find the total miles he walked. 2. **Analyze the given information:** The park is shaped like a right triangle with sides 1.6 mi (vertical leg), 2.3 mi (horizontal leg), and 2 mi (hypotenuse). 3. **Find the perimeter of the park:** The perimeter $P$ of a triangle is the sum of all its sides. $$P = 1.6 + 2.3 + 2$$ 4. **Calculate the perimeter:** $$P = 1.6 + 2.3 + 2 = 5.9$$ miles 5. **Calculate total distance walked:** Pete walked around the park three times, so multiply the perimeter by 3. $$\text{Total distance} = 3 \times 5.9 = 17.7$$ miles 6. **Final answer:** Pete walked **17.7 miles** in total.
