Question 467767: a boat can travel 51 mph in still water. if it travels 480 miles with the current in the same length of time it travels 336 miles against the current, what is the speed of the current? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! Boat speed = 51 mph
current speed = x mph
speed against current 51 - x
speed with current 51 + x
Distance against wind 336 miles
Distance with wind 480 miles
t=d/r time against = time with
336/(51-x)=480/(51+x)
336(51+x)=480(51-x)
17136+336x=24480-480x
480x+336x= 7344
816 x = 7344
/ 816
x = 9 mph current speed
