the jet stream is a wind current that flows across the US from west to east. Flying with the jet stream, an airplane flew 2700 miles in 4.5 hours. Against the same wind, the return trip took 6 hours. Find the speed of the plane in stil air and the speed of the jet stream.
Answers: 3
) is equal to sum of the absolute velocity of the jet steam 
and the relative velocity of the airplane with respect to jet stream (velocity of the airplane in still air) (
). Al velocities are measured in miles per hour. Let suppose that both jet stream and airplanes travels at constant velocity. Now, we construct the following system of linear equations:
(1)
(2)
