Solve with a complete explanation of each step that you are doing. Be sure to make a diagram so anyone can tell what the variables correspond to. If you have another real life problem that you can apply calculus to, you can submit that solved problem instead. Remember, the very first thing you need to do is draw a picture of the situation and clearly label the variables associated with your picture. 2. One ship was sailing south at the rate of 6 mi per hr. Another ship was sailing east at the rate of 8 mi per hr. At 4 pm the second crossed the track of the rst where the rst had been 2 hr before. How was the distance between the ships changing at 3 pm? How was the distance changing at 5 pm? When was the distance between them not changing? Make a plot with x(t), y(t) and s(t) when t = 3, 5, and when ds/dt = 0. Make a plot with t on the x-axis and s on the y-axis. Does the minimum value of ds/dt on your graph correspond to value of t that you computed? (yes or no)
