SOLUTION: an air traffic controller is tracking two planes. to start, plane A is at an altitude of 5000 feet and plane B is at an altitude of 4467 feet. Plane A is gaining altitude at 40.5 f

Question 931513: an air traffic controller is tracking two planes. to start, plane A is at an altitude of 5000 feet and plane B is at an altitude of 4467 feet. Plane A is gaining altitude at 40.5 feet per second and plane B is gaining altitude at 50.75 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?
Answer by josgarithmetic(39617) (Show Source): You can put this solution on YOUR website!
Plane A, 5000+40.5x
Plane B, 4467+50.75x
x is number of seconds of time.

When altitudes equal?

seconds.
Use either formula for altitude of a plane to find what the altitude would be.
