Question

if you followed the 70 degrees W line of longitude north to the north pole and then continued on the same line south, what line of longitude would you bee in?

Answer 1

The line of longitude that continues the line longitude 70 degrees W line past the north pole is the 110 degrees E line

Step-by-step explanation:

The line of longitude which the 70 degrees W line continues as is the 110 degrees East as we move past the north pole because the the difference in degrees between the initial line of 70 degrees W and the line of longitude being followed after crossing the north pole will be 180° as we have past half the rotation of the globe, which is 360°

Therefore, the line of longitude, x, being followed is therefore;

70 - 0 + x degrees east = 180°

Which gives;

70 + x degrees east = 180° degrees east

x degrees east = (180° - 70°) degrees east = 110° degrees east

x degrees east = 110° degrees east

Therefore, the line of longitude that continues the line longitude 70 degrees W line past the north pole is the 110 degrees E line.
