Let the speed of boat in still water and speed of stream be 'x' km/hr and 'y' km/hr, respectively. According to question; (170/x) - (120/x) = 5 Or, (50/x) = 5 So, x = 10 Now, 8 x (10 + y) = 8 x (10 - y) + 16 Or, 80 + 8y = 80 - 8y + 16 Or, 16y = 16 So, y = 1 So, downstream speed of the boat = (10 + 1) = 11 km/hr And, upstream speed of the boat = (10 - 1) = 9 km/hr Required time taken = (300/11) + (150/9) ~ (27 + 17) ~ 44 hours
