Dave and Sandy Hartranft are frequent flyers with a particular airline. They often fly from City A to City B, a distance of 816 miles. On one particular trip, they fly into the wind, and the flight takes 2 hours. The return trip, with the wind behind them, only takes 1 1 2 hours. If the wind speed is the same on each trip, find the speed of the wind and find the speed of the plane in still air.
