Flying against the wind, an airplane travels 2750 kilometers in 5 hours. flying with the wind, the same plane travels 6090 kilometers in 7 hours. what is the rate
of the plane in still air and what is the rate of the wind?
rate of the plane in still air:
ola
1x
s
?
rate of the wind:

The rate of airplane in still air

The rate of the wind is  

Step-by-step explanation:

Let the speed of the airplane be

And the speed of the wind be  

So we know that,

According to the question.

When the airplane is flying with the wind it will be supported by the wind.

So the speed,  

                       ...   equation (1)

When the airplane is flying with against the wind it will be negated by the wind.

Then the speed , ...   equation (2)

 Plugging the values from equation (1)....

So rate of airplane in still air

Now to find the rate of wind we can plug the values of rate of airplane in equation (1).

Then we have

So the rate of the wind that is  

The rate of airplane in still air and rate of the wind is  

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
