Aweather plane took to the skies to measure the speed of the jet stream. the plane flew 1920 km with the jet stream as a tail wind. then, it returned to its original location. the eastbound flight took 2 hours, and the westbound flight took 3.2 hours. which system of equations can be used to find the speed of the jet stream and the speed of the plane? what was the speed of the jet stream? (p = plane, w = wind) a) p + w = 960; p - w = 600; jet stream's speed = 180 km/h b) p + w = 960; p - w = 500; jet stream's speed = 180 km/h c) p - w = 960; p + w = 600; jet stream's speed = 200 km/h d) p + w = 960; p - w = 600; jet stream's speed = 160 km/h

Apassenger on a jet plane is wondering why the flight times on her ticket are so different. her flight from los angeles to boston took five hours and 20 minutes; however, her return flight from boston back to los angeles takes nearly six hours. how can you explain the difference to this passenger? as she travels from la to boston, she will be traveling against the gulf stream so the flight speed will be slower. as she travels from boston to la, she will be traveling against the jet stream so her flight time will be longer. as she travels from boston to la, she will be traveling with the jet stream so her travel time will be longer. her plane has been delayed.
