At noon, ship A was 16 nautical miles due north of ship B. Ship A was sailing south at 16 knots (nautical miles per hour; a nautical mile is 2000 yd) and continued to do all day. Ship B was sailing east at 11 knots and continued to do so all day. Complete parts (a) through (e) below. a. Start counting time with t=0 at noon and express the distances between the ships as a function of t. s(t) = b. How rapidly was the distance between the ships changing at noon? One hour later? At noon the distance between the ships was changing at a rate of One hour later, the distance between the ships was changing at a rate of c. The visibility that day was 5 nautical miles. Did the ships ever sight each other? O No OYes ds d. Graph s and together as functions of t for 1st≤ 3. Compare the graphs and reconcile what you see with your answers in parts (b) and (c). Select the correct
