2 Three rivers R R2 and R3 merge together to form a river R4 The cross sectional areas of the three rivers R R2 and R3 are in the ratio 1 2 3 and speed of water flowing in these are in the ratio 1 Assuming streamline flow if R4 has cross sectional area equal to that of R the ratio of speed of water in R4 to that in R is A 4 1 B 3 1 C 2 1 D 1 1
