An airplane cruises northeast at a steady rate. Its speed can be broken down into two components:320 miles per hour due north and 40 milers per hour due north be the direction of the positive y-axis and let due east be the direction of the positive x-axis. Write parametric equations to model the location of the plane. Then graph the equations. What is the position of the plane 15 minutes after reaching cruising altitude?
