  1. You need some specific information. How far south of the lighthouse is the ship? How far north of the lighthouse is it supposed to be? What do you know about the ship's speed?
  2. Figure out the total distance the ship has to travel. The ship travels 30 miles in one hour. How many hours will it take to travel the total distance?
  3. The ship will take several hours to get to where it‚Äôs supposed to be. Divide the total distance by the speed of the ship to find the time needed.
