Two airplanes are in flight near a local airport. One plane is at an altitude of 1000 meters and is ascending at a rate of 400 meters per minute. The second plane is at an altitude of 5900 meters and is descending at a rate of 300 meters per minute. 

Make a graph to determine when the planes will be at the same altitude.

At 7 minutes, the planes will be at the same altitude.
