Homework Help: Physics

Posted by Anonymous on Tuesday, February 26, 2008 at 6:02pm.

A small boat is crossing a river which flows at 10km.h. The driver of the boat keeps it heading directly (at 90) away from the bank at a speed of 24 km/h relative to the water. The river is 0.5 km wide.

I calculated the speed of the boat relative to land - 26km/h
I calculated the direction the boat is actually traveling - 67* from bank
I calculated the time to get to the opposite bank - 1.25min

How far downstream will the boat drift before reaching the opposite bank?

How do I calculate that. ^
