You can put this solution on YOUR website! A river has a current of 6 kilometres per hour. A canoeist travels downstream for 1.5 hours and returns in 5 hours. Determine the one-way distance travelled.
***
let x=speed of canoeist in still water
x+6=speed of canoeist downstream
x-6=speed of canoeist upstream
travel time*speed=distance
..
1.5(x+6)=5(x-6)
1.5x+9=5x-30
3.5x=39
x=39/3.5≈11.14
5(x-6)=5*5.14=25.71
one-way distance travelled≈25.71 km
