I don't believe there is a 313 7th Street in Manhattan, so I think you must be asking about 313 7th Street in Brooklyn.
For one thing, you did not say "East 7th Street" or "West 7th Street" as is customary with Manhattan addresses. Of course, it's possible you just forgot. But I don't think there even IS a West 7th Street in Manhattan, and the street numbers on East 7th Street don't seem to go up to 313.
So I think you must be talking about 313 7th Street in Brooklyn, which is in the neighborhood known as Park Slope. The zip code is 11215.
The zip code for Avenue A at 3rd Street is 10009.

New York City's
The most famous street in New York City is probably Broadway. Other possibilities are Fifth Avenue, Madison Avenue, Park Avenue, and Wall Street.
Assuming you are traveling north in a straight line, the distance would be roughly a third of a mile. In New York City, 17 to 20 street blocks equals a mile, and 5 to 10 avenue blocks equals a mile (the length of the avenue blocks varies considerably, depending on what neighborhood you're in).
Radio City Music Hall is located at 1260 Avenue of the Americas (6th Avenue is also called Avenue of the Americas). It is on the corner of 50th Street and 6th Avenue.
Fifth Avenue is the dividing line between the West and East Sides of Manhattan, not New York City. There is no street or avenue that divides all of New York City into west and east.
