Question 1021145: a girl paddles her kayak upstream from her home to her friends home taking 2 1/2 hours for the journey.she returns that afternoon in 1 1/2 hours.
if the river is flowing at 2 1/2 km/h find:
A.her paddling speed in still water
B.the distance to her friends place Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! Assuming the distances upstream and downstream are the same, then:
2.5(x-2.5)kmh=1.5(x+2.5)kmh
2.5x-6.25=1.5x+3.75
1x=10 kmh in still water......
1.5(10+2.5)=18.75 kilometers to her friend's house!!!!!!
