The speed of the stream is 10 km/h. Boat ‘A’ covers 110 km distance against the stream in 11 hours and boat ‘B’ covers 65 km distance against the stream in 2 hours. The speed of boat ‘B’ in still water is how much percent of the speed of boat ‘A’ in still water?
Speed of boat ‘A’ upstream = 110/11 = 10 km/h Speed of boat ‘B’ upstream = 65/2 = 32.5 km/h Speed of the boat ‘A’ in still water = 10 + 10 = 20 km/h Speed of the boat ‘B’ in still water = 32.5 + 10 = 42.5 km/h Required percentage = (42.5/20) × 100 = 212.5%
