At 5:00 am airplane #1 has an elevation of 9000 ft. and is climbing at the rate of 150 ft/min. At 5:35 am, airplane #2 is at an elevation of 32160 and is descending at the rate of 300 ft/min.

Question

(1) Let  represent the time in minutes since 5:00 am, and let  represent the elevation in feet. Write an equation for the elevation of each plane in terms of .plane #1: 9000+150Correct  plane #2: 32160−300t

(2) At what time will the two airplanes have the same elevation?

Incorrect ? minutes after 5:00am  

(3) What is the elevation at that time? ? feet  

NEED HELP ANSWER IS NOT 32160-300t



Answer 1

#! E(t) = 9000 + 150t

#2 E(t) = 32160 - 300(t - 35)

9000 + 150t = 32160 - 300(t - 35)

Can you solve for t and answer?

To determine elevation substitute above value for t in either function.
