Question

A passenger jet can fly 804 miles in 2 hours with tailwind but only 776 miles in 2 hours into a headwind. Find the speed of the jet in still air and the speed of the wind

Answer 1

In a hour tailwind flies 402 mph
In a hour headwind flies 388 mph

Answer 2

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.
