Concept explainers
To calculate : The airspeed of the airplane and the speed of the wind.
Answer to Problem 77E
The airspeed of the airplane and the speed of the windare
Explanation of Solution
Given information :
Total distance covered by the airplane between New York city and Albuquerque
Time take by the airplane to travel between New York city and Albuquerque
Time take by the airplane to travel betweenAlbuquerque and New York city
Calculation :
Suppose the airspeed of the airplane be
Assuming the wind is blowing from Albuquerque and New York city. The direction of wind will remain constant.
Since, the airplane is flying from New York city to Albuquerque, the net speed of airplane is calculated as
Now, according to the question:
Similarly, the airplane is flying from Albuquerque to New York city, the net speed of airplane is calculated as
Solve equation (1) and (2):
Calculate value of
Therefore, the airspeed of the airplane and the speed of the windare
