Question

Traveling to Vietnam,a plane encounters a tailwind and averages 289 mph.However ,on the return trip the plane , now traveling against the same wind averages 257mph. Find the speed of the wind and the speed of the plane in no wind

Answer 1

2 * plane speed in still air = 289mph + 257mph = 546
plane speed in still air = 273 mph

plane speed in still air + wind speed = 289
273 + wind speed = 289
Therefore, wind speed = 16 mph

Answer 2

The answer to your question is 16 mph
