Question

A transcontinental flight of 4160 km is scheduled to take 52 min longer westward than eastward. The airspeed of the airplane is 945 km/h, and the jet stream it will fly through is presumed to move due east. What is the assumed speed of the jet stream?

Please include an explanation, and define any variables. Thanks.

Answer 1

If the plane is moving in eastward, the ground speed is, So, the time is 1 as If the plane is moving in westward, the ground speed is, gs So, the time is 2 The time difference is, 2ah 2dv 60 minVaV 13 2dv 1 h 52 min

From the above equation, the speed of the jet stream is, 13(945 kmh)-13v, -30(4160km), 1.16x10 km2 / -13v -0.013x10'v, 0 131, +0.0 13 x10'y,-1.16 107-0 (vs-88.45 )(V)s +10088.45-0 v,88.45 km/h
