Solving a Flight Time with Wind: What to Calculate?

[HTT]

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?
