Question

Prime Meridian & International Date Line

Answer 1

Answer:

Greenwich

Explanation:

The International Date Line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway round the world from the prime meridian—the zero degrees longitude established in Greenwich, England, in 1852.

Answer 2

Explanation:

All the meridians are helpful to locate time.

the meridian at greenwich,england, is the prime meridian and it is the base for all the other times

the gap between prime meridian and India standard meridian (IST) is +5h 30 min

for example the time at prime meridian is 12:00 pm (England)

then time in india is ....

12:00+ 5h 30 min

so the time in India is 5:30 pm

in this way we calculate the time for which the prime meridian is the base

the prime meridian is at 180°

for each meridian there is 4 min time gap..

I hope this explanation is ok for you if so comment me
