Quizplus · Accepted Answer

Using the Pythagorean theorem, the distance "as the crow flies" can be found by taking the square root of the sum of the squares of the horizontal and vertical distances:
sqrt((3.6)^2 + (2.8)^2) ≈ 4.6
Rounding to the nearest whole number, the answer is 5 miles, which is option D.
