An air traffic controller is tracking two planes. To start, Plane A was at an altitude of890 meters, and Plane B was at an altitude of1322 meters. Plane A is losing altitude at 16 meters per second, and Plane B is losing altitude at25 meters per second.

An air traffic controller is tracking two planes. To start, Plane A was at an altitude of890 meters, and Plane B was at an altitude of1322 meters. Plane A is losing altitude at 16 meters per second, and Plane B is losing altitude at25 meters per second. Expression which shows altitude of plane after x seconds.

Equation to show when they'll both be at the same altitude

890 - 16x ; 1322 - 25x ; 9x = 432 = x = 48

Step-by-step explanation:

Plane A:

Altitude = 890 m

Altitude loss = 16 m per second

Plane A:

Altitude = 1322 m

Altitude loss = 25 m per second

Equation :

Altitude - (altitude loss * time)

Plane A:

890 - 16x

Plane B:

1322 - 25x

Plane A = Plane B

890 - 16x = 1322 - 25x

-16x + 25x = 1322 - 890

9x = 432

x = 432 / 9

x = 48 seconds
