Determine the meridian of the Western Hemisphere, along which the plane will fly from the South Pole

Determine the meridian of the Western Hemisphere, along which the plane will fly from the South Pole, if before that it flew along the meridian 63 * E.

In order to find the answer to this question, you need to carefully read the text and drop its essence. In fact, the question is which meridian of the western hemisphere is an extension of the 63 * meridian of the eastern hemisphere. To solve this problem, it is necessary to remember the degree network of the globe and the location of the meridians. The continuation of the initial meridian is the 180 * meridian. This means that the distance between pairs of meridians, one of which is a continuation of the other, is 180 *. Let’s make an equation and make calculations:
63 * + x = 180 * x = 180 * – 63 * x = 117 *
Answer: the plane will fly to the meridian 117 * west.
