Two airplanes are flying in the air at the same height. Airplane A is flying east at 230 mi/h and airplane B is flying north at 270 mi/h. a. Take the derivative of the Pythagorean Theorem, a2 + b2 = c2 with respect to t. b. If they are both heading to the same airport, located 44 miles east of airplane A and 33 miles north of airplane B, at what rate is the distance between the airplanes changing? Answer exactly. The distance is shrinking at a rate of mi/h. Hint: The phrase "shrinking at a rate" implies the rate of change is negative so do not enter a negative number as your answer.

Person A is 10 km south of person B. A walks north at a speed of 2 km/h. B walks east at a speed of 3 km/h. If they both start at 2:00 p.m., determine the closest distance they will ever be from each other and the time this occurs. Draw on the diagram to support your opening equation. [8 marks]

An air traffic controller spots two airplanes at the same altitude converging to a point as they fly at right angles to each other. One airplane is 90 miles from the point and has a speed of 450 miles per hour. The other is 120 miles from the point and has a speed of 600 miles per hour. Part (a) At what rate is the distance between the planes changing? Part (b) How much time does the controller have to get one of the airplanes on a different flight path?
