What Does [N30.0'E] Indicate in Navigation Terms?

In summary, the conversation discusses a pilot wanting to fly her plane to a lake 250.0km away in a specific direction. The conversation includes calculations for the direction the pilot should head and her velocity relative to the ground. The poster also asks for clarification on the meaning of the direction provided.

Hey i would appreciate if some1 is able to help me out here... this is the question:
A pilot wants to fly her plane to a lake that is 250.0km [N30.0'E] from her starting point. The plane has an air speed of 210.0km/h, and a wind is blowing from the west at 40km/h.
a) Calaculate in what direction should she head the plane to fly directly to the lake
b) If she uses the heading determined in (A), what will be her velocity relative to the ground?
It seems simple but the answer to the question is not the same one that i am getting. (Answer in the book is a) N20.5'E
& the answer to (B) is:
b) 227 km/h [N30.0'E]
Any help would be appreciated!

Is this on a flat Earth or on a sphere?

What does [N30.0'E] mean? 30 degrees north of east? or 30 degrees east of north?
 

1. What is relative velocity?

Relative velocity is the velocity of an object in relation to another object. It takes into account the movement and position of both objects.

2. How is relative velocity calculated?

Relative velocity is calculated by subtracting the velocity of one object from the velocity of the other object. This results in the relative velocity, which takes into account the motion and direction of both objects.

3. What is the difference between relative velocity and absolute velocity?

Absolute velocity is the velocity of an object with respect to a fixed point, while relative velocity takes into account the motion of two objects in relation to each other. Absolute velocity is constant, while relative velocity can change depending on the motion of both objects.

4. Can relative velocity be negative?

Yes, relative velocity can be negative. This means that the two objects are moving in opposite directions, with one object having a greater velocity than the other.

5. Why is relative velocity important in physics?

Relative velocity is important in physics because it helps us understand the motion of objects in relation to each other. It allows us to calculate the speed and direction of an object, taking into account the motion of another object. This is crucial in fields such as mechanics, astronomy, and fluid dynamics.
