Because there are 360 degrees in a circle. The world is assumed to be a globe that is formed from 360 degrees.
There are 360 longitudes
The same as the total number of different lengths that can be measured on a3-foot ruler. If you name two longitudes, then no matter how close togetherthey are, I can always name another longitude that's in between yours. Sothere's no limit to the number of different longitudes that we can name.
Because you must go all the way around the Earth in order to cross every possible longitude, but you only need to go half-way around it ... pole to pole ... in order to stand at every possible latitude. And by the way . . . there are an infinite number of longitudes, that cover a range of 360 degrees, and an infinite number of latitudes, that cover a range of 180 degrees.
Because when you travel in longitude, you can go all the way around the Earth, 360 degrees, crossing new longitudes all the way . But when you travel in latitude, the farthest you can travel is from one pole to the other pole ... halfway around the Earth, 180 degrees. Once you reach the opposite pole, if you keep going farther, you're just crossing latitudes that you've already crossed once.
as all the places on the same longitude have their noon at the same time
At the poles.
to the nearest minute between longitudes 60e31 & 74e53 & between latitudes 29n22 & 38n29
Latitudes are parallel to the equator. Longitudes converge like elastics on a soccer ball.

They aren't, latitudes are.
False. The United States stretches across multiple longitudes, from around 67 degrees west in the easternmost point to 125 degrees west in the westernmost point. So, it is not entirely in the west longitudes.
