Help with a math problem!!! I am stumped – College Algebra?

This is verbatum from my quarterly test:

“A boat moves 5 kilometers upstream in the same amount of time it moves 17 kilometers downstream. If the rate of the current is 6 kilometers per hour, find the rate of the boat in still water.”

That’s it… No multiple choice… Just gotta find the answer. Thanks! (I already took the test, but this is the only one that stumped me)

d=rt…..r is km/hr

5= ( r + 6 )t…..

17= ( r – 6 )t

5 = rt + 6t 1]

17= rt – 6t 2]

1] + 2}

22=2rt ….r= 11/t…the rate is 11km/hr…verify yourself
