wo small planes approach an airport, one flying due west at 110 mi/hr and the other flying due north at 140 mi/hr. Assuming they fly at the same constant elevation, how fast is the distance between the planeschanging when the westbound plane is 180 miles from the airport and the northbound plane is 230 miles from the airport? Don’t forget to draw diagrams and show your work. Round your final calculationto one decimal place. Your answer should be a sentence.
