Flying against the wind, an airplane travels in hours. Flying with the wind, the same plane travels in hours. What is the rate of the plane in still air and what is the rate of the wind?

Rate of the plane still in the air= ____km/h
Rate of the wind= ____km/h

check your typing, you state no units of time.

To solve this problem, we need to set up a system of equations using the given information.

Let's denote the rate of the plane in still air as "P" (in km/h) and the rate of the wind as "W" (in km/h).

When the plane flies against the wind, it travels for "x" hours. The speed of the plane relative to the ground (against the wind) is the difference between the rate of the plane and the rate of the wind (P - W). Therefore, the distance traveled against the wind can be expressed as:
Distance = Rate × Time
Distance = (P - W) × x

Similarly, when the plane flies with the wind, it travels for "y" hours. The speed of the plane relative to the ground (with the wind) is the sum of the rate of the plane and the rate of the wind (P + W). Therefore, the distance traveled with the wind can be expressed as:
Distance = Rate × Time
Distance = (P + W) × y

Given the information, we have:
(P - W) × x = Distance
(P + W) × y = Distance

We know the time it took for both scenarios, so we can substitute the given values to get:
(P - W) × x = (P + W) × y

From this equation, we can simplify and solve for P and W. Let's do that:

Px - Wx = Py + Wy
Px - Py = Wy + Wx
P(x - y) = W(x + y)

Now, we can solve for the rate of the plane in still air (P) by dividing both sides by (x - y):

P = (W(x + y))/(x - y)

This equation gives us the rate of the plane in still air (P) in terms of the rate of the wind (W) and the given time values.

Unfortunately, without knowing the specific values of x and y, we cannot determine the exact numerical values of P and W. However, if you provide the time values for flying against the wind and with the wind, I can calculate the rate of the plane in still air and the rate of the wind for you.
