Speed = distance time. Also, it is given that Ritu can row downstream 20 km in 2 hours. ⇒ x + y = 20 2 = 10 ⇒ x + y = 10 - (1) Similarly, it is given that Ritu can row upstream 4 km in 2 hours. ⇒ x − y = 4 2 = 2 ⇒ x − y = 2 - (2) Now we need to solve equations ( 1) and ( 2). Adding ( 1) AND ( 2) ,we get. x + y + x − y = 12 ⇒ 2 x = 12 ⇒ x = 6 km/hr.
