What state is at 20 degrees north and 157 degrees west

Well, the water is 65 km and its 40 miles from land, and Hawaii is near water and 40 miles from land, so the correct answer would be Hawaii.

The continental US goes until about 125 Degrees west: the rest of the states are more to the East, for example, Masschusets is between 70 and 75 degrees West.

More to the west are only Alaska and Hawaii, but Alaska is much more to the north.

So the correct answer is: Hawaii!
