## Homework Statement

Two ships, one moving 15 degree west of north with a speed 25 mi/h., the second moving 25 degree south of west with a speed 20 mi/h. relative to water pass each other. Find the velocity of the second ship relative to the first ship (magnitude and direction).

## Homework Equations

V1 + r = V2

V2 - V1 = r

## The Attempt at a Solution

I want to confirm on this.

My approach is using this relation.

V1 + r = V2

and so V2 - V1 = r, where r is the velocity we are looking for of our problem.

Then I will take components, x and y, and find sqrt(x^2+y^2) and direction tan-1 y/x
