Answer:

sqrt(149) or about 12.21

Step-by-step explanation:

Think of the islands as coordinates on a graph. If the harbor is the origin, the first island would be (-7,2) while the second island would be (3,-5). To find the distance you have to use the Pythagorean theorem, so 10^2+7^2=d^2. This shows you that the distance has to be the square root of 149, or around 12.21 (rounding to the nearest hundredth).
