Upstream speed = 294/7 = 42 km/h Downstream speed = 486/9 = 54 km/h Speed of boat in still water = (42 + 54)/2 = 48 km/h Speed of stream = (54 – 42)/2 = 6 km/h Increased speed of boat in still water = 48 + 4 = 52 km/h Decreased speed of stream = 6 – 2 = 4 km/h Required time taken = 720/(52 – 4) + 616/(52 + 4) = 15 + 11 = 26 hours
