I got this question in a text book and i don't really know what it is asking(adsbygoogle = window.adsbygoogle || []).push({});

Here is the question:

A submarine is travelling due east and heading straight for a point P. A battleship is travelling due south and heading for the same point P. Both ships are travelling at a velocity of 30km/hr. Initially, their distances from P are 210km for the submarine and 150km for the battleship. How close will the two vessels come to each other????

Is the question asking intial distance or do i need to find a rule that relates them then find the distance. i don't know what it is meant. any insight to this question would be greatly appreciated.

Thanx :)
