latitude go to= and longitude go to=?

Question

i need help to prove teacher that he wrong

Answer 1

Latitude is the measure north or south of the equator. It only goes from the equator to the pole which is 1/4 of the way around the world, so the max is 90 degrees.

Longitude is the measure east or west of the prime meridian. It goes half the way around the globe, so the max is 180 degrees.

Answer 2

In addition to Ecolink contribution, I will add that the degrees of latitude and longitude are divided in 60 minutes where one minute of latitude is the definition of the nautical mile or 1852 meters. Since longitudes are not parallel, you need to multiply your distance in minutes by the cosine of the latitude. For example since cosine 60 = 0.5, a degree of longitude at latitude 60 north or south is half a nautical mile, or 926 meter.
If you want to find a distance you need to use Pythagoras: The square root of the sum of the square of latitude plus the square of longitude. This only works for small distances. When you need to calculate a distance over several degrees of longitude or latitude, you need first to decide if you are going to follow the great circle (gnomonic navigation) which is the shortest, or the compass heading (rhumb line), which is the longest.
All transoceanic vessels follow the shortest route, of course, and this is the reason the Titanic didn't sail west to go from Southampton the New York, but described - on a Mercator projection map - a circle that took it north and into the iceberg belt.
