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) = 240/12 = 20 km/hr Or, 25 – y = 20 Or, y = 25 – 20 = 5 km/hr Therefore, downstream speed of the boat = 25 + 5 = 30 km/hr Required time taken = 177/30 = 5.9 hours
