Not sure if you are supposed to consider Coriolis and/or Earth's curvature for the range. Given that it is only about 1km, probably not.
But I should think you are to give the answer as latitude and longitude. You may have to consider curvature for that.

Please do not post working as images. Those are for diagrams and textbook extracts. Take the trouble to type it in.
Also, try to work purely symbolically, only plugging in numbers at the end. There are many advantages, not least that it makes it much easier for others to follow your logic. Rememeber to define your variables.

Here's a little brighter version of your image, but haruspex is right -- it's better to type your work into the forum in your future posts here. Thanks.

And it's even better when you use LaTeX.
