Answer:
10.8 mi
Explanation:
Picture a right triangle with legs 9 mi and 6 mi. Applying the Pythagorean Theorem (d² = a² + b²), we get:
(9 mi)² + (6 mi)² = 117 mi²
This is the square of the hypotenuse (the desired distance).
Taking the square root of both sides, we get d = √(117 mi) ≈ 10.8 mi = d
The desired straight line distance traveled is 10.8 mi
