Question

An airplane can fly at a rate of 560 mph in calm air. It can fly 2400 miles with the wind at the same time it can fly 2080 miles against the wind. Solve for the speed of the wind.

Answer 1

Why does it fly faster against the wind than in calm air?

Answer 2

idk that is the question in the book

Answer 3

Just read this and it makes sense.
It can fly 2400 miles with the wind at the same time it can fly 2080 miles against the wind.

Answer 4

I can fly further with the wind than against it....just what you would expect.

Answer 5

*It not I

Answer 6

Distance traveled with the wind\[D _{1}\]Distance traveled against the wind\[D _{2}\]Speed of the plane in calm air
\[S _{p}\] Speed of wind\[S _{w}\]Distance traveled= speed x time (t)\[D _{1}=(S _{p}+S _{w})t\]\[D _{2}=(S _{p}-S _{w})t\]
we know the distance traveled with and against wind, and the speed of the plane. Solve for the spped of the wind.

Answer 7

*speed not spped

Answer 8

I would solve for t in each equation and then substitute for t.

Answer 9

What would be the equation then?

Answer 10

for the question
