Question -

Ritu can row downstream 20 km in 2 hours and upstream 4 km in 2 hours. Find her speed of rowing in still water and the speed of the current.



Answer -

Let the speed of rowing in still water = x km/hr
and speed of current of water = y km/hr
Speed of downstream = (x + y) km/hr
and speed of upstream = (x – y) km/hr
Speed of rowing = 6 km/hr and speed of current = 4 km/hr
