If the speed of water is A km/hr and speed of a boat in still water is B km/hr, then speed upstream and speed downstream respectively will be:-(A > B)

If the speed of the man in still water is 6 km/hr, find how much he can row downstream in 10 hours. Speed of upstream = 30 / 6 = 5 km / hr. Speed of man in still water = 6 km / hr. ∴ Speed of current = 6 – 5 = 1 km / hr.
If the speed of the man in still water is 6 km/hr, find how much he can row downstream in 10 hours. Speed of upstream = 30 / 6 = 5 km / hr. Speed of man in still water = 6 km / hr. ∴ Speed of current = 6 – 5 = 1 km / hr.
