Step-by-step explanation:
After travelling two hours, the two cruise ships form a triangle. One of the legs of this triangle will be the distance Cruise A travelled, and another will be the distance Cruise B travelled. We can find the distance they travel using:

Cruise A is travelling at 18 miles per hour for 2 hours. Therefore, Cruise A has travelled:

Cruise B is travelling at 15 miles per hour for 2 hours. Therefore, Cruise B has travelled:

Because we are given the angle between these legs, we can use the Law of Cosines to find the third leg. The Law of Cosines is given by:
, where
,
, and
are interchangeable. Let
represent the distance between the two cruises. We have:
(one significant figure).
