My teacher always says : "Lattitude goes up and down, longitude goes 'round and 'round."
And if ur still confused, remember how we talk bout compasses. Eg. "I was sound east." You don't say "I was east of south." Coz that sounds funny.
The north /south bit comes first coz it tells you the hemisphere (which, supposedly is more important).
Then the east/west (I think the median line is the same as time zones, as in, the origin is at Greenwich, England).
So something like 20 S 70 E
Or whatever the answer was. (omg, people remembered their answers on multiple choice... I feel dumb).
Yeah... so I'm pretty sure I got it right... I like, had my teacher singing in my head for that q.
One more test to go... then we're FREEE!!!!
