1. Two airplanes leave an airport at the same time on different runways. One flies on a bearing of N 66.5W at 325 miles per hour. The other airplane flies on a bearing of S 26.5W at 300 miles per hour. How far apart will the airplanes be after two hours?

2.

16x² + 25y² 96x + 100y 156 = 0 is the equation of an ellipse. Convert this equation to standard form by completing the square on x and y. Then graph the ellipse and state the coordinates of the foci.

I need the answers and also the detail explanation for each step of these questions. Thank you for helping.
