1. Dave and Sandy Hartranft are frequent flyers with Delta Airlines. They often fly from
Philadelphia to Chicago, a distance of 780 miles. On one particular trip, they fly into the wind,
and the flight takes 3 hours. The return trip, with the wind behind them, only takes 2 hours. If
the wind speed is the same on each trip, write the system of equations that would be used to find
the speed of the wind and speed of the plane in still air. Be sure to label what your variables
represent first. You do not need to solve the system.
