Answer: 12.6 miles

Step-by-step explanation:

Here the ship is doing a circular path.

We know that the ship is 120° from the north, and we want to find the distance that the ship has traveled so far from the most northern tip of the island.

This distance will be equal to the length of the arc of 120°

You can find this as:

Arc = (angle*3.14/180)*radius

arc = (120*3.14/180)*6 miles  = 12.56 miles

Now we need to round it to the nearest tenth, so we need to round it up, and we get 12.6 miles
