Solving a Flight Time with Wind: What to Calculate?

Click For Summary
To solve the flight time difference between two airports with and without wind, first calculate the time taken for a 300 km flight at an airspeed of 970 km/h without wind. Then, adjust the airspeed to account for the wind speed of 220 km/h, which will affect the effective speed of the airplane. The difference in flight times will provide the answer to the original question. Understanding the relationship between velocity, distance, and time is crucial for these calculations. Completing these steps will clarify the impact of wind on flight duration.

Homework Statement


One of my question asks that: How much longer is the flight from airport A to B with the wind as indicated than with no wind... I don't get its meaning. What do I need to solve for this question?

It sounds like you need to solve for the difference in time a flight from A to B takes depending upon the specified wind conditions. But we can't really tell unless you present the actual question.

The original question is : An airplane is to fly directly from airport A to Airport B, a distance of 300km. The airspeed of the plane is 970km/hr. The wind blows to the airplane at a constant speed of 220km/hr.

So, seems straightforward. Calculate the flight time with no wind and then again with the wind. The difference in time is what they're looking for.

What equations do you know that relate velocity, distance, and time?

:) Thanks a lot~ Finally finished all my homework...
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
