A plane can fly 290 miles downwind in the same amount of time as it can travel 220 miles upwind. Find the velocity of the wind i

nikitadnepr [17]

Answer:

The speed of the wind is $35\ mph$

Step-by-step explanation:

Let

x-----> the speed of the wind in mph

we know that

Downwind

$(255+x)=\frac{290}{t}$

$t=\frac{290}{(255+x)}$ -----> equation A

Upwind

$(255-x)=\frac{220}{t}$

$t=\frac{220}{(255-x)}$ ----> equation B

equate the equation A and the equation B

$\frac{290}{(255+x)}=\frac{220}{(255-x)}\\ \\290(255-x)=220(255+x)\\ \\ 73,950-290x= 56,100x+220x\\ \\220x+290x=73,950-56,100\\ \\510x=17,850\\ \\x= 35\ mph$
