## Homework Statement

A boat capable of making 12.0 km/h in still water is used to cross a river flowing at speed of 2.0 km/h. The boat is directed (from the perpendicular to the shore) in such a way that its resulting motion is straight across the river.

At what angle (in degrees) must the boat be directed?

What is the resultant speed relative to the shore?

## Homework Equations

That's the problem I am having. I have no clue how to set up this problem (I'm extremely new to physics).

## The Attempt at a Solution

Again, no attempt yet because I am stuck on set up. Which is really all I need help with--just figuring out how to set it up, not the math. Thanks :)
