Question

How many degrees of a full circle can you travel eastward or westward from the zero (prime) Meridian before heading back toward the Prime Meridian?
a. 60 degree.
b. 90 degree.
c. 360 degree.
d. 180 degree.
e. none of the above.

Answer 1

Lines of longitude that are utilized to help represent a spherical coordinate system that travels from 180 degrees eastward or westward of the (zero) Prime Meridian Line.

Lines of latitude are parallel and get shorter as they reach the poles, while Lines of longitude remain the same length when they reach the poles.

Here one degree is equal to sixty-nine miles (69 miles).

Hence the answer is option “d”.

Answer 2

180° the back to back rotation towards prime meridian
