Hello oG riT. Welcome to PF !

To answer your question, you need to use trigonometry.

Is that question worded exactly as it was given to you in the textbook?

 

[Ace.]

Use Tan function to find the angle. (θ represents an angle)
Tanθ = opp/adj
= 4km / 3km
θ = tan^-1(4km/3km)

So the direction would be [N θ E]

yes that's how it was worded
