Ship Crossing - Ship A travels south at a speed of B mii'hour, and ship El travels east at a speed of 15 miihour. At 3" AM the ships are positioned as seen in the picture. Plot the distance between the ships as a function oftime for the next 4 hours. The horizontal axis should show.r the actual time of dajlr starting at TAM, while the 1rI'erlical axis shows the distance. Label the axes. Ii visibility is 8 miles, estimate from the graph the time when people from the two ships can see each other. 14 miles 25 miles Swimming - The following chart shows some old 100 meter free-style Olympic gold medal swimming records by year for men. Fit as many different types of trendlines as you can to the data. Plot each and indicate the best fitting trendline.
