At 6:00 am airplane #1 has an elevation of 3500 ft. and is climbing at the rate of 100 ft/min. At 6:35 am, airplane #2 is at an elevation of 28200 and is descending at the rate of 400 ft/min. (1) Let tt represent the time in minutes since 6:00 am, and let E represent the elevation in feet. equation for the elevation of each plane in terms of t. plane #1: E(t)= plane #2: E(t))= (2) At what time will the two airplanes have the same elevation? t=__________ minutes after 6:00 am (3) What is the elevation at that time? E=_________ feet
