Question 26014: Could you please help me with this problem: The excursion boat "Holiday" travels 35 km upstream and then back again in 4hours and 48 minutes. If the speed on the "Holiday" in still water is 15 km/h, what is the speed of the current?
Thank you. Answer by Paul(988) (Show Source):
You can put this solution on YOUR website! 4 hours and 48 minutes = 4.8hours
Still water speed = 15
Speed with the current = 15+x
Speed against the current = 15-x
total distance == 35
