Two ships are sailing in the fog and being tracked on a small screen. At some point in time, t=0, the first ship, the Andy Daria (AD), is at a point 900 mm from the bottom left corner of the screen along the lower edge. The other ship, the Helinski (H), is located at a point 100 mm above the lower left corner along the left edge. One minute later, the AD has moved to a location that is 3 mm west and 2 mm north of the previous location. The H has moved 4 mm east and 1 mm north. Assume that they will continue to move at a constant speed on their respective linear courses. Create an illustration of the situation. Create a parameterization for each of the vessels. Will the two ships collide if they maintain their speeds and directions? If so, when and where? Determine the minimum distance between the ships and the time at which they are the closest.
