(b)
Answer to Problem 41E
The value of
Explanation of Solution
Given:
The general equation is
Calculation:
Let the velocity of wind is
The airspeed of both planes is 200 mph in still air.
The airspeed of 1st plane moving along the direction of wind will be
The distance traversed by 1st plane moving along the direction of wind in t hr will be
The airspeed of 2nd plane moving against the direction of wind will be
The distance traversed by 2ndplane moving against the direction of wind in t hr will be
So, the problems are,
Divide the equation (1) by equation (2).
Further, solve the above problem.
Therefore, the speed of the wind is
