Against the wind a commercial airline in South America flew 630 miles in 3.5 hours. With a tailwind the return trip took 3 hours
Salsk061 [2.6K]

Answer:

The speed of plane is 195\ mph, and speed wind is 15\ mph.

Step-by-step explanation:

Given against the wind the airline flew 630 miles in 3.5 hours.

including the tailwind the return trip took 3 hours.

Let speed of plane is x.

Also, speed of the wind is y.

Now, we will find speed on each case.

Speed against the wind is  \frac{630}{3.5}=180\ mph

Speed with the wind is \frac{630}{3}=210\ mph

Now, we will write the equation

x+y=210\\x-y=180

Add these equation we get,

2x=390\\x=\frac{390}{2}\\x=195\ mph

Now, plug this value in x+y=210 to get speed of wind

195+y=210\\y=210-195\\y=15\ mph

So, the speed of plane in still air is 195\ mph, and speed of the wind is 15\ mph.
