    There's an equation in my notes that says distance=AB/angle but when I substitute the values into the equation the answer is wrong. d=(2000x10^3) divided by 0.3. The answer is supposed to be D.

    Remember when using  s = r\theta for the arc length, \theta is in radians!

    Still doesn't give me the right answer...I did 2000 divided by (0.3 x pi/180). Then doubled r, but still the wrong answer.

    You're doing something wrong.

    \dfrac{2000}{\left(\dfrac{0.3\pi  }{180}\right)} = 381972 \approx 3.82\times 10^5 \, \,km
