Question

A plane travels 210 mph in still air. It takes 2 hours longer to travel 425 miles flying against the wind then it does flying with the wind. Find the speed of the wind.

Answer 1

Round to nearest tenth

Answer 2

\[t = \frac{d}{r}\]
\[\frac{425}{210-w} - \frac{425}{210+w} = 2\]

Answer 3

So it's just 2?

Answer 4

???
No you have to algebraically solve for "w", which represents speed of wind
