A cruise boat travels 48 miles downstream in 3 hours and returns upstream in 12 hours. Find the rate of the stream. I will check tomorrow morning before I head off to schoool. I am definitely going to bed now. Thanks. Bye.

I will check tomorrow morning before I head off to schoool. I am definitely going to bed now. Thanks. Bye. Let the speed of the boat in still water be b, and the speed of the current be w, then: 3=48/(b+w), 12=48/(b-w). As b+w is the speed going down stream, and b-w is the speed going upstream. RonL
That's the answer that I have. just needed to check.
