Let the speed of boat in still water be x km/hr and the distance be y km. Rate downstream = (x + 3.5) km/hr Rate upstream = (x – 3.5) km/hr According to the question, y/(x + 3.5) = 2 --- (i) y/(x – 3.5) = 5/2 --- (ii) On dividing equation (i) by (ii), (x – 3.5)/(x + 3.5) = 2/(5/2) = 4/5 5x – 16.5 = 4x + 15 x = 16.5 + 15 = 31.5 kmph
