In this problem, it does not matter, in which direction the balloon is moving.
It can move south, north, west, and the solution method along the answer will be the same.
The important fact is that the balloon moves horizontally along a straight line
at constant altitude over the horizontal Earth surface.
When a Math problem has excessive words, its always makes an unpleasant impression.
It shows clearly that the author is not a professional Math writer and produces his tasks on his knee in the garage.
There is nothing bad in producing problems on a knee in a garage,
but there is no need to demonstrate it to the world.
A truly mathematical problem is a piece of art and shines like a temple on a hill.
