Three rivers R₁, R₂ and R₃ merge together to form a river, R₄ . The cross sectional areas of the three rivers R₁, R₂ and R₃ are in the ratio 1: 2: 3 and speed of water flowing in these are in the ratio 1: 1 2 : 1 3 . Assuming streamline flow, if R₄ has cross sectional area equal to that of R₁ , the ratio of speed of water in R₄ to that in R₁ is
