Paddling with the current, a canoeist can travel 30 km in 5 hours. Against the current, the canoeist takes 6 hours and 15 minutes to travel the same distance. Find the rate of the canoeist in still water and the rate of the current. ​

30 km / 5hr = 6 km/hr

30 km / 6.25hr = 4.8 km/hr

 

in still water    ( 6+ 4.8)/2 = 5.4 km hr in still water

current =   6 - 5.4 = .6 km/hr        or     5.4 - 4.8 = .6 km/hr
