Respuesta :
In a hour tailwind flies 402 mph
In a hour headwind flies 388 mph
In a hour headwind flies 388 mph
Answer:
The jet goes 395 mph in still air, the wind speed is 7mph.
Step-by-step explanation:
Just average 402 and 388, giving you 395 (speed in still air). Then, find the difference between that speed and the headwind/tailwind speed (395-388=7) giving you 7 (the wind speed). The wind accelerated the jet by 7mph on the tailwind and deccelerates it by 7mph on the headwind.
