1. An airplane flying horizontally at an altitude of 1 mile passes directly over an observer. The plane is flying at 240 mph. How fast is the distance between the plane and the observer changing 30 seconds later? Make sure you follow the following steps for full credit. Draw the picture. Label all constants and variables. Define all variables (Example: Let x = distance of the woman from the pole, y= distance travelled by ship A. These are only examples and not related to the given problem). Create a table with variables and the rates of change. Write down what is given and what you need to find. Write a relationship between the variables and then solve the
