Let the speed of the boat in still water and the speed of the current be ‘x’ km/hr and ‘y’ km/hr, respectively Upstream speed of the boat = (x – y) = 120/12 = 10 km/hr Or, 15 – y = 10 Or, y = 15 – 10 = 5 km/hr Therefore, downstream speed of the boat = 15 + 5 = 20 km/hr Required time taken = 120/20 = 6 hours
