At 6:00 am airplane #1 has an elevation of 25400 ft and is descending at the rate of 250 ft/min. At 6:20 am, airplane #2 takes off from its runway (elevation = 0 ft) and climbs at the rate of 350 ft/min. (1) Let t represent the time in minutes since 6:00 am, and let E represent the elevation in feet. Write an 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? ime will the two airplanes t = minutes after 6:00 am (3) What is the elevation at that time? E = feet
