Question
The speed of the stream is 14 km/h. Boat βAβ covers
64 km distance against the stream in 4 hours and boat βBβ covers 95 km distance against the stream in 5 hours. The speed of boat βBβ in still water is how much percent of the speed of boat βAβ in still water?Solution
Speed of boat βAβ upstream = 64/4 = 16 km/h Speed of boat βBβ upstream = 95/5 = 19 km/h Speed of the boat βAβ in still water = 16 + 14 = 30 km/h Speed of the boat βBβ in still water = 19 + 14 = 33 km/h Required percentage = (33/30) Γ 100 = 110%
