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) = 140/7 = 20 km/hr Or, 28 – y = 20 Or, y = 28 – 20 = 8 km/hr Therefore, downstream speed of the boat = 28 + 8 = 36 km/hr Required time taken = 180/36 = 5 hours
