Question 633969: a boat takes the same amout of time to go 14 miles upstream as it does to go 16 miles downstream. if the current of the river is 2 mph, what is the speed of the boat in still water? Answer by mananth(16946) (Show Source):
Time with current= 14 hours
time against current 16 hours
Distance = same d=rt
14(x+2) =16(x-2)
14x+28=16x-32
14x-16x =-32-28
-2 x= -60
x = 30 mph Boat speed
