An air traffic controller is tracking two planes. to start, plane a is at an altitude of 3427 feet and plane b is at an altitude of 5000 feet. plane a is gaining altitude at 65.75 feet per second and plane b is gaining altitude at 35.5 feet per second. how many seconds will pass before the planes are at the same altitude? what will their altitude be when they're at the same altitude.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
