Question

Answer 1

$\huge\underline{\underline{\mathfrak \red{Answer}}}$

❏They start at the Prime Meridian (or 0 degrees) and measure from 0 degrees to 180 degrees east and 180 degrees west.

❏ Also, the two lines connect at 180 degrees or at the International Date Line. This too helps to determine the different time zones throughout the world.

Answer 2

Explanation:

Time is kept from an imaginary line running through Greenwich, England, called the Prime Meridian. The International Date Line is an imaginary line located halfway around the world at roughly 180 degrees longitude that separates one day from the next. If you cross the International Date Line, the date changes.
