Then the boat turns around and returns with the current. What still-water speed should the captain use to complete the tour in 5 hours? : Dear Student, I think I interpreted this problem wrong. It seems they want to know the speed required to return to the beginning (60 mi) in 5 hrs : Let s = still water speed then (s+5) = speed downstream : Write a time equation: Time = Distance/speed : Time down stream = 5 h = 5 : Multiply equation by (s+5) to get rid of the denominators, results: 60 = 5(s+5) : 60 = 5s + 25 : 5s = 60 - 25 5s = 35 s = 35/5 s = 7 mph still water speed to return in 5 hours : : Check by finding the distance going (7+5) mph for 5 hrs 12*5 = 80; confirms our solution : I truly regret giving you wrong information.
