Round-Trip Speed Word Problem help?

I'm having trouble and been stuck for half an hour just trying and erasing and I need some help.

Question: In still water, Sarah's boat can travel 15 km/h. If it takes her a total of 4 1/2 hours to travel 30 km up a river and then to return by the same route, what is the speed of the current in the river?

I have posted a link there to this thread so the OP can view my work.
