Plane A is descending toward the local airport, and plane B is ascending from the same airport. Plane A is descending at a rate of 2,500 feet per minute. Plane B is ascending at a rate of 4,000 feet per minute. If plane A is currently at an altitude of 14,000 feet and plane B is at an altitude of 1,000 feet, how long will it take them to be at the same altitude? The equation representing plane A’s descent is y = -2,500x + 14,000. The equation representing plane B’s ascent is y = 4,000x + 1,000. In both equations, y represents altitude and x represents time in minutes.
Part A
Go to your math tools and open the Graph tool to graph the two equations and determine the position of the point of intersection for the two equations. To create the graph, select the correct relationship and then enter the values for the variables. Adjust the maximum and minimum y-values until the point of intersection is visible. Paste a screenshot of the graph in your answer.
