Question 346881: An airliner flying with the wind takes 3.5 hours to fly 1,875 miles and 4 hours to fly the same distance against the wind. Assuming that the airliner travels at a constant speed and the wind blows at a constant rate, find the speed of the airliner in still air and the wind speed. Round off the answers to two decimal places.
