According to the measurements I got from Google Maps, they are approximately 9 miles (14.5 kilometers) apart as the crow flies (meaning, if you were to draw an imaginary straight line between the two).
It's very, very close. The Bronx is directly across the bay known as the Long Island Sound from LaGuardia. The distance between them, as the crow flies (meaning, if you were to draw a straight, imaginary line on the map between the two) is about 2.5 miles.
The distance in road miles is roughly 5 to 5.5 miles. That's the distance from LaGuardia, along the Triboro Plaza (which is what the Grand Central Parkway turns into after it passes LaGuardia heading west), over the Robert F. Kennedy Bridge, over Randall's Island, and into the south Bronx, where the road diverges into the Major Deegan Expressway (heading west) and the Bruckner Expressway (heading northeast).
Not from inside the Newark Airport, but looking out the window of a departing or arriving flight from Newark International Airport, a view of the New York Harbor, including the Statue of Liberty, is visible.
15 miles
There isn't an airport in the Bronx but the nearest airport is LaGuardia Airport.
